10x-5\left(x+1\right)-2\left(x-2\right)=20
Multiply both sides of the equation by 10, the least common multiple of 2,5.
10x-5x-5-2\left(x-2\right)=20
Use the distributive property to multiply -5 by x+1.
5x-5-2\left(x-2\right)=20
Combine 10x and -5x to get 5x.
5x-5-2x+4=20
Use the distributive property to multiply -2 by x-2.
3x-5+4=20
Combine 5x and -2x to get 3x.
3x-1=20
Add -5 and 4 to get -1.
3x=20+1
Add 1 to both sides.
3x=21
Add 20 and 1 to get 21.
x=\frac{21}{3}
Divide both sides by 3.
x=7
Divide 21 by 3 to get 7.
