20+4x-4-5x+2\left(x+1\right)=0
Use the distributive property to multiply 4 by x-1.
16+4x-5x+2\left(x+1\right)=0
Subtract 4 from 20 to get 16.
16-x+2\left(x+1\right)=0
Combine 4x and -5x to get -x.
16-x+2x+2=0
Use the distributive property to multiply 2 by x+1.
16+x+2=0
Combine -x and 2x to get x.
18+x=0
Add 16 and 2 to get 18.
x=-18
Subtract 18 from both sides. Anything subtracted from zero gives its negation.
