84\times 3=m\times 36
Variable m cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 84m, the least common multiple of m,84.
252=m\times 36
Multiply 84 and 3 to get 252.
m\times 36=252
Swap sides so that all variable terms are on the left hand side.
m=\frac{252}{36}
Divide both sides by 36.
m=7
Divide 252 by 36 to get 7.
