Solve for x: 66=7/12x + 30

OpenStudy (cp123):

Can someone help? I dont remember how to do opposite operations with fractions.

OpenStudy (hdrager):

All you have to do is isolate x right?

OpenStudy (cp123):

yeah. but i dont remember how to with fractions. I know you subtract the 30, so then you would get 36=7/12x

OpenStudy (cp123):

but i dont remember how to isolate further

OpenStudy (cp123):

wait wouldnt you multiply 36 by 12 and then divide it by 7?

OpenStudy (royalranger):

yep

OpenStudy (cp123):

okay thank you. so it would be 61.7

OpenStudy (royalranger):

plug it back into the original equation and see if you get 66
