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