100\times 12=x\times 75
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 100x, the least common multiple of x,100.
1200=x\times 75
Multiply 100 and 12 to get 1200.
x\times 75=1200
Swap sides so that all variable terms are on the left hand side.
x=\frac{1200}{75}
Divide both sides by 75.
x=16
Divide 1200 by 75 to get 16.
