12=-4\left(x-7\right)
Variable x cannot be equal to 7 since division by zero is not defined. Multiply both sides of the equation by x-7.
12=-4x+28
Use the distributive property to multiply -4 by x-7.
-4x+28=12
Swap sides so that all variable terms are on the left hand side.
-4x=12-28
Subtract 28 from both sides.
-4x=-16
Subtract 28 from 12 to get -16.
x=\frac{-16}{-4}
Divide both sides by -4.
x=4
Divide -16 by -4 to get 4.
