x-6=-x\times 3
Variable x cannot be equal to any of the values 0,6 since division by zero is not defined. Multiply both sides of the equation by x\left(x-6\right), the least common multiple of x,6-x.
x-6=-3x
Multiply -1 and 3 to get -3.
x-6+3x=0
Add 3x to both sides.
4x-6=0
Combine x and 3x to get 4x.
4x=6
Add 6 to both sides. Anything plus zero gives itself.
x=\frac{6}{4}
Divide both sides by 4.
x=\frac{3}{2}
Reduce the fraction \frac{6}{4} to lowest terms by extracting and canceling out 2.
