9+x\left(-6\right)=12x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
9+x\left(-6\right)-12x=0
Subtract 12x from both sides.
9-18x=0
Combine x\left(-6\right) and -12x to get -18x.
-18x=-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-9}{-18}
Divide both sides by -18.
x=\frac{1}{2}
Reduce the fraction \frac{-9}{-18} to lowest terms by extracting and canceling out -9.
