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