4x - 2x - 2 = -42

OpenStudy (mertsj):

What is 4x-2x?

OpenStudy (anonymous):

2x?

OpenStudy (anonymous):

-2x, I mean.

OpenStudy (mertsj):

So now your equation says 2x-2=-42. So add 2 to both sides. What do you get?

OpenStudy (anonymous):

2x=-40

OpenStudy (anonymous):

Then divide by 2?

OpenStudy (mertsj):

Now divide both sides by 2

OpenStudy (anonymous):

-20!

OpenStudy (mertsj):

Good job!!

OpenStudy (anonymous):

Yay! Thank you!
