2+m\times 4=20m
Variable m cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by m.
2+m\times 4-20m=0
Subtract 20m from both sides.
2-16m=0
Combine m\times 4 and -20m to get -16m.
-16m=-2
Subtract 2 from both sides. Anything subtracted from zero gives its negation.
m=\frac{-2}{-16}
Divide both sides by -16.
m=\frac{1}{8}
Reduce the fraction \frac{-2}{-16} to lowest terms by extracting and canceling out -2.
