okay :)
OpenStudy (anonymous):
im back
OpenStudy (anonymous):
k :) whats your next problem?
OpenStudy (anonymous):
um x/-4 + 5 =1
OpenStudy (anonymous):
Okay, the first thing to do is to combine like terms. How do you think you can do that? We want to combine numbers that look alike.

OpenStudy (anonymous):
nothing looks alike
OpenStudy (anonymous):
Okay. Since the 5 has no x by it that means we can combine it with the 1. We do this by subtracting 5 from each side. Try this and tell me what you think the new equation would look like
OpenStudy (anonymous):
i think it is x/-4 = -4
OpenStudy (anonymous):
Perfect! You got this! Next we need to isolate the variable (x) by multiplying each side by -4. What does the equation look like now? And can you find the answer? :)
OpenStudy (anonymous):
i dnt understand

OpenStudy (anonymous):
is it -4
OpenStudy (anonymous):
Okay, thats okay too. So our equation looks like this: x/-4 = -4. Since x is being divided by the -4 we need to get the x by itself and multiply x/-4 times -4 which would give us x.
since we multiplied one side by -4 we multiple the other side by -4. And since two negatiavies that are mupltiplied by each other equal a positive your answer is x = 16
OpenStudy (anonymous):
yes i was rite
OpenStudy (anonymous):
yep :) good work!
OpenStudy (anonymous):
yes wanna help me with more n im srry if im bugging u i just dnt get this stuff

Its all good :) I will help you all you need, and your not bugging me. You will get it soon!
OpenStudy (anonymous):
k here is another one
OpenStudy (anonymous):
-7 = c/-6 + 12
OpenStudy (anonymous):
Okay, the process is just like the other one. Do you see any like terms that we can combine?
OpenStudy (anonymous):
do we mulitply -6 n -7

OpenStudy (anonymous):
We will, but that is our second step.
OpenStudy (anonymous):
ok then do u subtract 12 from both sides
OpenStudy (anonymous):
YES! :) your getting it! :)))) good job!
OpenStudy (anonymous):
so then it would be -19 = c/-6
OpenStudy (anonymous):
Correct! What is our second step now?

OpenStudy (anonymous):
do u multiply by -6
OpenStudy (anonymous):
Yep! :) on both sides
OpenStudy (anonymous):
so the answer is c = 114
OpenStudy (anonymous):
Yes!!!! :)
OpenStudy (anonymous):
yay! lol here is another one x/4x - 7 = 8

OpenStudy (anonymous):
okay :) what do we do first?
OpenStudy (anonymous):
i have no clue
OpenStudy (anonymous):
No problem! We start out like we did before by combining like numbers. So since the -7 and the 8 are not connected to any x's we can combine them
OpenStudy (anonymous):
So what would our new equation look like?
OpenStudy (anonymous):
its subract 7 noot -7
Still Need Help?

OpenStudy (anonymous):
Opps :) okay. So since the 7 is being subtracted we can add 7 to each side. So the new equation would be x/4x = 15
OpenStudy (anonymous):
then u would multiply 4 to each side rite
OpenStudy (anonymous):
yep!
OpenStudy (anonymous):
so the answer would be x=60
OpenStudy (anonymous):
Correct!!! :)

-12 = 6 + 2/3 y
OpenStudy (anonymous):
Okay! How do we start? Do you know the first step?
OpenStudy (anonymous):
subtract 6?
OpenStudy (anonymous):
you got it!
OpenStudy (anonymous):
the new equation would be -18 = 2/3y

Yes! :) Now have you learned how to divide fractions?
OpenStudy (anonymous):
nope
OpenStudy (anonymous):
Okay, no problem. So to divide by a fraction we have to actually multiple by the reciprocal. This means that instead of dividing by 2/3 from each side, we multiply each side by 3/2. The reciprocal just basically means the opposite of the fraction. Does that make sense?
OpenStudy (anonymous):
so does tht mean y = 27
OpenStudy (anonymous):
Close. Since 18 is negative y = -27 :)

-17 = -32 - 3/5f
OpenStudy (anonymous):
Okay, so how do we start? Do yo remember? :)
OpenStudy (anonymous):
umm do we add -17 n -32
OpenStudy (anonymous):
yep!!! :) brb
OpenStudy (anonymous):
ok

OpenStudy (anonymous):
okay, im back
OpenStudy (anonymous):
ok so the new equation would be -49 - 3/5f
OpenStudy (anonymous):
Since we have to add the 32 that is negative to both sides we add it, so it is actually -17 + 32 which would be 15 :) but you got the right idea
OpenStudy (anonymous):
so it would b 15 - 3/5f
OpenStudy (anonymous):
yep! :) now we multiply each side by the reciprocal to get f by itself

OpenStudy (anonymous):
huh?
OpenStudy (anonymous):
since the equation is 15 = -3/5f we have to multiply each side by the reciprocal of -3/5 which would be 5/3. that would cancel out the right side, and on the left side we would have 15 times 5/3 = f
OpenStudy (anonymous):
so the answer would be f = 25
OpenStudy (anonymous):
yep!!! good work!
OpenStudy (anonymous):
8 - 3/8 = -4

Are you sure thats the right question? Is there an x by one of the numbers?
OpenStudy (anonymous):
yea
iam not sure if thats right
OpenStudy (anonymous):
0.625 thats the answer not -4
OpenStudy (anonymous):
srry typed it wrong its 8 - 3/8k = -4 and christosc tht is the equation
OpenStudy (anonymous):
So do you remember what do first?

ahhhh add 8 n -4?
OpenStudy (anonymous):
yep :)
OpenStudy (anonymous):
soo now it would b 4 = 3/8k brb im crying need a tissue

im bak

Are you okay? okay

my bf cheated on me n some st.upid stuff so ok bak to the problem
OpenStudy (anonymous):
oh :( im sorry. okay. so now multiply by the reciprocal which would be 8/3 on both sides
OpenStudy (anonymous):
would the answer be 10 2/3
OpenStudy (anonymous):
yep!

k um -14 = s + 12/ -6

OpenStudy (anonymous):
okay. jas
OpenStudy (anonymous):
k
OpenStudy (anonymous):
So the first thing is we can simplify the fraction 12/-6. What would 12/-6 equal?
OpenStudy (anonymous):
-2
OpenStudy (anonymous):
perfect! now its a simple problem: -14 = s -2
Still Need Help?

OpenStudy (anonymous):
so u would multiply -14 n 2
OpenStudy (anonymous):
not quite. this time you would just add 2 to each side and there is your answer :)
OpenStudy (anonymous):
s = -12
OpenStudy (anonymous):
perfect! I have to go help my roommate clean the bathroom now, but if you need more help I will be back in about 30 min
OpenStudy (anonymous):
So sorry! you are doing really well tho!
