5\times 4=16x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10x, the least common multiple of 2x,5.
20=16x
Multiply 5 and 4 to get 20.
16x=20
Swap sides so that all variable terms are on the left hand side.
x=\frac{20}{16}
Divide both sides by 16.
x=\frac{5}{4}
Reduce the fraction \frac{20}{16} to lowest terms by extracting and canceling out 4.
