12-3x-\left(-4\right)=4
To find the opposite of 3x-4, find the opposite of each term.
12-3x+4=4
The opposite of -4 is 4.
16-3x=4
Add 12 and 4 to get 16.
-3x=4-16
Subtract 16 from both sides.
-3x=-12
Subtract 16 from 4 to get -12.
x=\frac{-12}{-3}
Divide both sides by -3.
x=4
Divide -12 by -3 to get 4.
