15\times 6=4x
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.
90=4x
Multiply 15 and 6 to get 90.
4x=90
Swap sides so that all variable terms are on the left hand side.
x=\frac{90}{4}
Divide both sides by 4.
x=\frac{45}{2}
Reduce the fraction \frac{90}{4} to lowest terms by extracting and canceling out 2.
