solve for x?

Answer 2

\(\Huge\cal\rlap{\color{magenta}{Welcome~to~Openstudy!{\heartsuit}}}{\color{red}{\; Welcome~to~Openstudy!{\heartsuit}}}\)

Answer 3

subtract 5 from both sides

Answer 4

cam you just going to give them the answer?

Answer 5

First You would subtract 5 from both sides:
5-21x = 2
-5 -5
You get:
-21x = -3
Then Divide by -3
-21 ÷ -3
x = 7

Answer 14

yeah like ask them questions instead of giving them the answer. Also i wasn't being rude

Answer 15

So after subtracting both sides by 5 what next?

Answer 16

You called me a derp lol... That's Like... Mean lol...

Answer 17

then explain to them what rules are being applied.

Answer 18

I told him. You subtract 5 from both sides then divide by -21 by -3

Answer 19

but you gave him/her the solution

Answer 20

I gave them an explanation

Answer 21

Now please, Stop Bickering with your pointless arguement

Answer 22

or could have given them another example instead of the answer

Answer 23

Why would i give them another example? Lol

Answer 24

why are you carrying on the convo?

Answer 25

to not give them the solution

Answer 26

You just carried it on... Lol...

Answer 27

Ive stopped, Just please stop arguing

Answer 28

do you learn my giving the solution? The solution as in how to solve the problem. If I was giving you several problems on integrals or derivatives with all the solutions would you understand how to apply addition, sub, product rule, quotient rule, chain rule, etc?

Answer 29

no you would just copy the answer down...

Answer 30

I wouldnt lol... I don't know about you since you are obviously stating you mentality as that

Answer 31

a lot of ppl do that on OS... They don't want to learn they just want the darn answer.

Answer 36

Only way is by avoiding them

Answer 37

Lol

Answer 38

when people ask me to solve a calc problem I get all antsy. I end up just giving them the solution to the problem and forget that i didn't teach them one thing. Lol

Answer 39

@job34 do you have any questions about your... Question?

Answer 40

@camerondoherty please explain how you can divide by -3 if it is not being multiplied to anything. Rather, you should just divide by -21 have the answer be x=3/7

Answer 41

No
-21x = -3
You divide
-21/-3 = 7
x = 7
Since you are multiplying by x you do the Inverse Operation by both sides
Thats why you divide

Answer 42

No, again, in order to isolate X you must divide by -21, If you do not, you will simply find that the equation simplifies to 7x=1, which, when you isolate X will lead you to the answer, 1/7. @camerondoherty (Sorry about my mistake above, it has been a very relaxed summer for me)
