15\times 17=13x
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.
255=13x
Multiply 15 and 17 to get 255.
13x=255
Swap sides so that all variable terms are on the left hand side.
x=\frac{255}{13}
Divide both sides by 13.
