8x-1-3\left(x-2\right)=-5\left(1+x\right)
Combine x and 7x to get 8x.
8x-1-3x+6=-5\left(1+x\right)
Use the distributive property to multiply -3 by x-2.
5x-1+6=-5\left(1+x\right)
Combine 8x and -3x to get 5x.
5x+5=-5\left(1+x\right)
Add -1 and 6 to get 5.
5x+5=-5-5x
Use the distributive property to multiply -5 by 1+x.
5x+5+5x=-5
Add 5x to both sides.
10x+5=-5
Combine 5x and 5x to get 10x.
10x=-5-5
Subtract 5 from both sides.
10x=-10
Subtract 5 from -5 to get -10.
x=\frac{-10}{10}
Divide both sides by 10.
x=-1
Divide -10 by 10 to get -1.
