20-2\left(2x-1\right)=7x
Multiply both sides of the equation by 10, the least common multiple of 5,10.
20-4x+2=7x
Use the distributive property to multiply -2 by 2x-1.
22-4x=7x
Add 20 and 2 to get 22.
22-4x-7x=0
Subtract 7x from both sides.
22-11x=0
Combine -4x and -7x to get -11x.
-11x=-22
Subtract 22 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-22}{-11}
Divide both sides by -11.
x=2
Divide -22 by -11 to get 2.
