Question

Please help me I'm clueless!!!!!!

Answer 1

@TheSmartOne @pooja195 @AlexandervonHumboldt2 @Compassionate @sleepyjess please help

Answer 2

hi

Answer 3

So, we need to solve the equation for y.
We need y to be by itself on the lefthand side of the equation

Answer 4

5y-5?

Answer 5

waittttt...
first we need y by itself
so
first step is to subtract 4x on both sides.

Answer 6

Isolate the y just like @UsukiDoll said then you reciprocal it and you get the equation of the line.
For example:
3/4x - 2y = 5
Isolate the y
so
-2y = -3/4 x + 5
Isolate the y
y = (-3/4x + 5) / 2
is the equation of the line.

Answer 7

Hope that helped.

Answer 8

im sorry, like i said, im clueless, even with you helping me, im awful at this

Answer 9

You still don't get it? Do you need another example??

Answer 10

it couldnt hurt

Answer 11

Okay lol lets start it simply shall we?
3x + y = 6
You are solving for an equation of the line which is y = mx + b
Since we don't have it in that form we have to change it into that form
So we isolate the y ( just like the formula of a line looks like)
so we bring the 3x on the other side.
So
y = -3x + 6 (the positive 3x becomes negative since we are brigning it on the other side)
(When you bring something to the other side the sign changes. So if it's addition on the left it becomes negative on the right and vice versus. If it's division on the other side then it's multiplication on the right side.

Answer 12

Now lets make it a teensy bit challenging okay?
2x + 3y = 12
Isolate the y (don't worry about the number in front of the y focus on isolating it first)
You bring 2x to the other side so
3y = -2x +12 (-2x because you brought to the right side)
NOW you isolate the y.
Y = (-2x + 12) / 3
(You divide it by three because in order to isolate the y you need to multiply the 3 by one third which gives you 1 so you get y by itself and 3 gets divided.)
(Whatever you do on the left you do the same thing on the right.)
(If you multiply 2 on the left then you multiply 2 on the right)

Sorry if I didn't help.

Answer 13

It's not your fault. I just am not good at any type of math that involves letters or words

Answer 14

Now lets go with "hard-hard"
1/2 x + 3/2y = 1
You isolate the y
So
3/2y = -1/2x + 1
In order to get rid of the coefficient in front of the y, you use reciprocal. So you multiply it by 2/3 on both sides and you get
y = 2(-1/2x + 1)/3

Did it help you though?? Cause that's the most important thing.

Answer 15

Oh yea, I hate word problems lol and Calculus is almost all about word problems XD

Answer 16

It helped as much as it could (for me at least) thank you

Answer 17

You sure? If you need more help I could try to give you a better break down of the problem.

Answer 18

no its fine

Answer 19

i dont want to waste your time

Answer 20

Okay so you can solve this problem or do you need me to solve this one problem for you?

Answer 21

Oh please don't worry about me, lol I get on here to answer questions...math ones mainly to refresh my memory and maybe solve/help some calculus students with theirs cause math is all about practice, the more practice I get the better it is for.

Answer 22

okay then if you can answer it that would be awesome

Answer 23

Lol okay
4x - 5y = 9
Isolate the 5y
-5y = -4x + 9
Now you isolate the y
y = -4/5x +9/5 <--- correct

Answer 24

Let me know if you need anymore help in the future lol peace.

Answer 25

this is the exact problem ive had before. that isnt an option

Answer 26

and i dont know why

Answer 27

hmmmm let me re look into the problem.

Answer 28

no, that answer is correct, but the choices dont list it

Answer 29

Oops! My fault!!!

Answer 30

y = 4/5x - 9/5
Is the right answer they didn't change the '-5' sign when they were dividing which in my opinion is mathematically incorrect but in order to get the right answer choice you don't change the sign for this, ask your teacher about the '-5' thing.

Answer 31

i have asked but she doesnt really have any control over these things unfortunately. thank you for your help though

Answer 32

No problem and well that's stupid. I am sorry that you have deal with that nonsense. ANyways, have a great day/night (lol wherever you live lol)

Answer 33

thanks. you too
