5\left(x-2\right)-20\left(x-3\right)-10\left(x-2\right)=-8\left(x+4\right)
Multiply both sides of the equation by 40, the least common multiple of 8,2,4,5.
5x-10-20\left(x-3\right)-10\left(x-2\right)=-8\left(x+4\right)
Use the distributive property to multiply 5 by x-2.
5x-10-20x+60-10\left(x-2\right)=-8\left(x+4\right)
Use the distributive property to multiply -20 by x-3.
-15x-10+60-10\left(x-2\right)=-8\left(x+4\right)
Combine 5x and -20x to get -15x.
-15x+50-10\left(x-2\right)=-8\left(x+4\right)
Add -10 and 60 to get 50.
-15x+50-10x+20=-8\left(x+4\right)
Use the distributive property to multiply -10 by x-2.
-25x+50+20=-8\left(x+4\right)
Combine -15x and -10x to get -25x.
-25x+70=-8\left(x+4\right)
Add 50 and 20 to get 70.
-25x+70=-8x-32
Use the distributive property to multiply -8 by x+4.
-25x+70+8x=-32
Add 8x to both sides.
-17x+70=-32
Combine -25x and 8x to get -17x.
-17x=-32-70
Subtract 70 from both sides.
-17x=-102
Subtract 70 from -32 to get -102.
x=\frac{-102}{-17}
Divide both sides by -17.
x=6
Divide -102 by -17 to get 6.
