5\times 36=4x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5x, the least common multiple of x,5.
180=4x
Multiply 5 and 36 to get 180.
4x=180
Swap sides so that all variable terms are on the left hand side.
x=\frac{180}{4}
Divide both sides by 4.
x=45
Divide 180 by 4 to get 45.
