-12x=\left(x-12\right)\times 4
Variable x cannot be equal to 12 since division by zero is not defined. Multiply both sides of the equation by 12\left(x-12\right), the least common multiple of 12-x,12.
-12x=4x-48
Use the distributive property to multiply x-12 by 4.
-12x-4x=-48
Subtract 4x from both sides.
-16x=-48
Combine -12x and -4x to get -16x.
x=\frac{-48}{-16}
Divide both sides by -16.
x=3
Divide -48 by -16 to get 3.
