mm-x=x\times 2
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by mx, the least common multiple of x,m.
m^{2}-x=x\times 2
Multiply m and m to get m^{2}.
m^{2}-x-x\times 2=0
Subtract x\times 2 from both sides.
m^{2}-x-2x=0
Multiply -1 and 2 to get -2.
m^{2}-3x=0
Combine -x and -2x to get -3x.
-3x=-m^{2}
Subtract m^{2} from both sides. Anything subtracted from zero gives its negation.
\frac{-3x}{-3}=-\frac{m^{2}}{-3}
Divide both sides by -3.
x=-\frac{m^{2}}{-3}
Dividing by -3 undoes the multiplication by -3.
x=\frac{m^{2}}{3}
Divide -m^{2} by -3.
x=\frac{m^{2}}{3}\text{, }x\neq 0
Variable x cannot be equal to 0.
