12x-4\times 2x-3\times 3x-72x=120
Multiply both sides of the equation by 12, the least common multiple of 3,4.
12x-8x-3\times 3x-72x=120
Multiply -4 and 2 to get -8.
4x-3\times 3x-72x=120
Combine 12x and -8x to get 4x.
4x-9x-72x=120
Multiply -3 and 3 to get -9.
-5x-72x=120
Combine 4x and -9x to get -5x.
-77x=120
Combine -5x and -72x to get -77x.
x=\frac{120}{-77}
Divide both sides by -77.
x=-\frac{120}{77}
Fraction \frac{120}{-77} can be rewritten as -\frac{120}{77} by extracting the negative sign.
