x\times 12=40\times 36
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 40x, the least common multiple of 40,x.
x\times 12=1440
Multiply 40 and 36 to get 1440.
x=\frac{1440}{12}
Divide both sides by 12.
x=120
Divide 1440 by 12 to get 120.
