3\times 5x-120\left(x-20\right)=4\left(-2x+18\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6.
15x-120\left(x-20\right)=4\left(-2x+18\right)
Multiply 3 and 5 to get 15.
15x-120x+2400=4\left(-2x+18\right)
Use the distributive property to multiply -120 by x-20.
-105x+2400=4\left(-2x+18\right)
Combine 15x and -120x to get -105x.
-105x+2400=-8x+72
Use the distributive property to multiply 4 by -2x+18.
-105x+2400+8x=72
Add 8x to both sides.
-97x+2400=72
Combine -105x and 8x to get -97x.
-97x=72-2400
Subtract 2400 from both sides.
-97x=-2328
Subtract 2400 from 72 to get -2328.
x=\frac{-2328}{-97}
Divide both sides by -97.
x=24
Divide -2328 by -97 to get 24.
