7=4-3x+12
Use the distributive property to multiply -3 by x-4.
7=16-3x
Add 4 and 12 to get 16.
16-3x=7
Swap sides so that all variable terms are on the left hand side.
-3x=7-16
Subtract 16 from both sides.
-3x=-9
Subtract 16 from 7 to get -9.
x=\frac{-9}{-3}
Divide both sides by -3.
x=3
Divide -9 by -3 to get 3.
