12=15x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
15x=12
Swap sides so that all variable terms are on the left hand side.
x=\frac{12}{15}
Divide both sides by 15.
x=\frac{4}{5}
Reduce the fraction \frac{12}{15} to lowest terms by extracting and canceling out 3.
