2\left(x-1\right)-4\left(x+2\right)=8+x+1
Multiply both sides of the equation by 8, the least common multiple of 4,2,8.
2x-2-4\left(x+2\right)=8+x+1
Use the distributive property to multiply 2 by x-1.
2x-2-4x-8=8+x+1
Use the distributive property to multiply -4 by x+2.
-2x-2-8=8+x+1
Combine 2x and -4x to get -2x.
-2x-10=8+x+1
Subtract 8 from -2 to get -10.
-2x-10=9+x
Add 8 and 1 to get 9.
-2x-10-x=9
Subtract x from both sides.
-3x-10=9
Combine -2x and -x to get -3x.
-3x=9+10
Add 10 to both sides.
-3x=19
Add 9 and 10 to get 19.
x=\frac{19}{-3}
Divide both sides by -3.
x=-\frac{19}{3}
Fraction \frac{19}{-3} can be rewritten as -\frac{19}{3} by extracting the negative sign.
