6x+30=-2\left(x+1\right)
Use the distributive property to multiply 6 by x+5.
6x+30=-2x-2
Use the distributive property to multiply -2 by x+1.
6x+30+2x=-2
Add 2x to both sides.
8x+30=-2
Combine 6x and 2x to get 8x.
8x=-2-30
Subtract 30 from both sides.
8x=-32
Subtract 30 from -2 to get -32.
x=\frac{-32}{8}
Divide both sides by 8.
x=-4
Divide -32 by 8 to get -4.
