600\times 45-200\times 90=x\times 125
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 600x, the least common multiple of x,3x,600.
27000-18000=x\times 125
Do the multiplications.
9000=x\times 125
Subtract 18000 from 27000 to get 9000.
x\times 125=9000
Swap sides so that all variable terms are on the left hand side.
x=\frac{9000}{125}
Divide both sides by 125.
x=72
Divide 9000 by 125 to get 72.
