Question 95384
3x-9=27
ok here is a good way to start i had problems with this kind of problems too dont worry and always come for help.

3x-9=27
you are going to have to move some numbers around like this

3x=9+27
you need to turn the 9 to positive because when its moved to the other side it changes signs

ok solve

3x=36
then since 3x is being multiplied you are going to have to to the opposite which is divide

x=12 and that is your answer
