4\times 3x-2\left(x-2\right)=40+x
Multiply both sides of the equation by 8, the least common multiple of 2,4,8.
12x-2\left(x-2\right)=40+x
Multiply 4 and 3 to get 12.
12x-2x+4=40+x
Use the distributive property to multiply -2 by x-2.
10x+4=40+x
Combine 12x and -2x to get 10x.
10x+4-x=40
Subtract x from both sides.
9x+4=40
Combine 10x and -x to get 9x.
9x=40-4
Subtract 4 from both sides.
9x=36
Subtract 4 from 40 to get 36.
x=\frac{36}{9}
Divide both sides by 9.
x=4
Divide 36 by 9 to get 4.
