15\times 3-12\times 6=22x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 60x, the least common multiple of 4x,5x,30.
45-72=22x
Do the multiplications.
-27=22x
Subtract 72 from 45 to get -27.
22x=-27
Swap sides so that all variable terms are on the left hand side.
x=\frac{-27}{22}
Divide both sides by 22.
x=-\frac{27}{22}
Fraction \frac{-27}{22} can be rewritten as -\frac{27}{22} by extracting the negative sign.
