12-3y=3\left(y-4\right)
Multiply both sides of the equation by 6, the least common multiple of 6,2.
12-3y=3y-12
Use the distributive property to multiply 3 by y-4.
12-3y-3y=-12
Subtract 3y from both sides.
12-6y=-12
Combine -3y and -3y to get -6y.
-6y=-12-12
Subtract 12 from both sides.
-6y=-24
Subtract 12 from -12 to get -24.
y=\frac{-24}{-6}
Divide both sides by -6.
y=4
Divide -24 by -6 to get 4.
