3\times 1200-1200=24x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of x,3x.
3600-1200=24x
Multiply 3 and 1200 to get 3600.
2400=24x
Subtract 1200 from 3600 to get 2400.
24x=2400
Swap sides so that all variable terms are on the left hand side.
x=\frac{2400}{24}
Divide both sides by 24.
x=100
Divide 2400 by 24 to get 100.
