0=m\times 16+4+m\left(-8\right)
Variable m cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by m.
0=8m+4
Combine m\times 16 and m\left(-8\right) to get 8m.
8m+4=0
Swap sides so that all variable terms are on the left hand side.
8m=-4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
m=\frac{-4}{8}
Divide both sides by 8.
m=-\frac{1}{2}
Reduce the fraction \frac{-4}{8} to lowest terms by extracting and canceling out 4.
