6x=8x+10 Answerr?!

OpenStudy (ipwnbunnies):

Get all the x terms to one side. Divide both sides by the number in front of the x term. Hint: Get the x's on the left side.

OpenStudy (anonymous):

ik and I always get the answer wrong hint jus give me the answer

OpenStudy (ipwnbunnies):

No, you can do this. What do you get when you move all the x's to the left side.

OpenStudy (anonymous):

14

OpenStudy (ipwnbunnies):

Subtract 8x from both sides.

OpenStudy (anonymous):

2?

OpenStudy (ipwnbunnies):

6x-8x = 8x + 10 -8x. We're trying to eliminate the 8x on the right side, so we have to subtract both sides by 8x.

OpenStudy (ipwnbunnies):

It'll be -2x, because 6x - 8x = -2, right?

OpenStudy (ipwnbunnies):

-2x*

OpenStudy (anonymous):

oh okay I see

OpenStudy (anonymous):

that was wrong

OpenStudy (ipwnbunnies):

Good, so -2x = 10. Nothing happened to the 10 yet b/c we were only working with the x terms.

OpenStudy (ipwnbunnies):

Well, we didn't solve for x yet.

OpenStudy (anonymous):

oh im stupid

OpenStudy (ipwnbunnies):

-2x = 10; how can we get x by itself now?

OpenStudy (anonymous):

dividing both sides by -2

OpenStudy (ipwnbunnies):

Good! What does that leave you.

OpenStudy (anonymous):

so would the answer be -5

OpenStudy (ipwnbunnies):

Yes, x = -5.

OpenStudy (anonymous):

im smart not really ha but thanks
