12x+8-4x-6=4x-6\left(x+1\right)+5x
Use the distributive property to multiply -2 by 2x+3.
8x+8-6=4x-6\left(x+1\right)+5x
Combine 12x and -4x to get 8x.
8x+2=4x-6\left(x+1\right)+5x
Subtract 6 from 8 to get 2.
8x+2=4x-6x-6+5x
Use the distributive property to multiply -6 by x+1.
8x+2=-2x-6+5x
Combine 4x and -6x to get -2x.
8x+2=3x-6
Combine -2x and 5x to get 3x.
8x+2-3x=-6
Subtract 3x from both sides.
5x+2=-6
Combine 8x and -3x to get 5x.
5x=-6-2
Subtract 2 from both sides.
5x=-8
Subtract 2 from -6 to get -8.
x=\frac{-8}{5}
Divide both sides by 5.
x=-\frac{8}{5}
Fraction \frac{-8}{5} can be rewritten as -\frac{8}{5} by extracting the negative sign.
