15\times 180-180=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.
2700-180=15x
Multiply 15 and 180 to get 2700.
2520=15x
Subtract 180 from 2700 to get 2520.
15x=2520
Swap sides so that all variable terms are on the left hand side.
x=\frac{2520}{15}
Divide both sides by 15.
x=168
Divide 2520 by 15 to get 168.
