x\times 1200=3000\times 1800
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3000x, the least common multiple of 3000,x.
x\times 1200=5400000
Multiply 3000 and 1800 to get 5400000.
x=\frac{5400000}{1200}
Divide both sides by 1200.
x=4500
Divide 5400000 by 1200 to get 4500.
