20x-5\left(x-1\right)+10x+20=2\left(x+1\right)+40
Multiply both sides of the equation by 10, the least common multiple of 2,5.
20x-5x+5+10x+20=2\left(x+1\right)+40
Use the distributive property to multiply -5 by x-1.
15x+5+10x+20=2\left(x+1\right)+40
Combine 20x and -5x to get 15x.
25x+5+20=2\left(x+1\right)+40
Combine 15x and 10x to get 25x.
25x+25=2\left(x+1\right)+40
Add 5 and 20 to get 25.
25x+25=2x+2+40
Use the distributive property to multiply 2 by x+1.
25x+25=2x+42
Add 2 and 40 to get 42.
25x+25-2x=42
Subtract 2x from both sides.
23x+25=42
Combine 25x and -2x to get 23x.
23x=42-25
Subtract 25 from both sides.
23x=17
Subtract 25 from 42 to get 17.
x=\frac{17}{23}
Divide both sides by 23.
