x\times 100=30\times 150
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 30x, the least common multiple of 30,x.
x\times 100=4500
Multiply 30 and 150 to get 4500.
x=\frac{4500}{100}
Divide both sides by 100.
x=45
Divide 4500 by 100 to get 45.
