45-15=10x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
30=10x
Subtract 15 from 45 to get 30.
10x=30
Swap sides so that all variable terms are on the left hand side.
x=\frac{30}{10}
Divide both sides by 10.
x=3
Divide 30 by 10 to get 3.
