15\times 240-270=15x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 15x, the least common multiple of x,15x.
3600-270=15x
Multiply 15 and 240 to get 3600.
3330=15x
Subtract 270 from 3600 to get 3330.
15x=3330
Swap sides so that all variable terms are on the left hand side.
x=\frac{3330}{15}
Divide both sides by 15.
x=222
Divide 3330 by 15 to get 222.
