15x+300=12\times 2x-120-20x
Multiply both sides of the equation by 60, the least common multiple of 4,5,3.
15x+300=24x-120-20x
Multiply 12 and 2 to get 24.
15x+300=4x-120
Combine 24x and -20x to get 4x.
15x+300-4x=-120
Subtract 4x from both sides.
11x+300=-120
Combine 15x and -4x to get 11x.
11x=-120-300
Subtract 300 from both sides.
11x=-420
Subtract 300 from -120 to get -420.
x=\frac{-420}{11}
Divide both sides by 11.
x=-\frac{420}{11}
Fraction \frac{-420}{11} can be rewritten as -\frac{420}{11} by extracting the negative sign.
