2\times 3\left(2x-2\times 5\right)-20x+20\times 5=5\left(2-x\right)
Multiply both sides of the equation by 10, the least common multiple of 5,2.
6\left(2x-2\times 5\right)-20x+20\times 5=5\left(2-x\right)
Multiply 2 and 3 to get 6.
6\left(2x-10\right)-20x+20\times 5=5\left(2-x\right)
Multiply 2 and 5 to get 10.
12x-60-20x+20\times 5=5\left(2-x\right)
Use the distributive property to multiply 6 by 2x-10.
-8x-60+20\times 5=5\left(2-x\right)
Combine 12x and -20x to get -8x.
-8x-60+100=5\left(2-x\right)
Multiply 20 and 5 to get 100.
-8x+40=5\left(2-x\right)
Add -60 and 100 to get 40.
-8x+40=10-5x
Use the distributive property to multiply 5 by 2-x.
-8x+40+5x=10
Add 5x to both sides.
-3x+40=10
Combine -8x and 5x to get -3x.
-3x=10-40
Subtract 40 from both sides.
-3x=-30
Subtract 40 from 10 to get -30.
x=\frac{-30}{-3}
Divide both sides by -3.
x=10
Divide -30 by -3 to get 10.
