4x-8=12x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
4x-8-12x=0
Subtract 12x from both sides.
-8x-8=0
Combine 4x and -12x to get -8x.
-8x=8
Add 8 to both sides. Anything plus zero gives itself.
x=\frac{8}{-8}
Divide both sides by -8.
x=-1
Divide 8 by -8 to get -1.
