9=-12x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
-12x=9
Swap sides so that all variable terms are on the left hand side.
x=\frac{9}{-12}
Divide both sides by -12.
x=-\frac{3}{4}
Reduce the fraction \frac{9}{-12} to lowest terms by extracting and canceling out 3.
