9\times 56=x\times 24
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 9x, the least common multiple of x,9.
504=x\times 24
Multiply 9 and 56 to get 504.
x\times 24=504
Swap sides so that all variable terms are on the left hand side.
x=\frac{504}{24}
Divide both sides by 24.
x=21
Divide 504 by 24 to get 21.
