15\times 5=x\times 25
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 15x, the least common multiple of x,15.
75=x\times 25
Multiply 15 and 5 to get 75.
x\times 25=75
Swap sides so that all variable terms are on the left hand side.
x=\frac{75}{25}
Divide both sides by 25.
x=3
Divide 75 by 25 to get 3.
