180\times 81-10\times 81=3x\times 36
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 180x, the least common multiple of x,18x,60.
14580-810=3x\times 36
Do the multiplications.
13770=3x\times 36
Subtract 810 from 14580 to get 13770.
13770=108x
Multiply 3 and 36 to get 108.
108x=13770
Swap sides so that all variable terms are on the left hand side.
x=\frac{13770}{108}
Divide both sides by 108.
x=\frac{255}{2}
Reduce the fraction \frac{13770}{108} to lowest terms by extracting and canceling out 54.
