2x+14-3\left(2-x\right)=4\left(-x-1\right)-6
Use the distributive property to multiply 2 by x+7.
2x+14-6+3x=4\left(-x-1\right)-6
Use the distributive property to multiply -3 by 2-x.
2x+8+3x=4\left(-x-1\right)-6
Subtract 6 from 14 to get 8.
5x+8=4\left(-x-1\right)-6
Combine 2x and 3x to get 5x.
5x+8=4\left(-x\right)-4-6
Use the distributive property to multiply 4 by -x-1.
5x+8=4\left(-x\right)-10
Subtract 6 from -4 to get -10.
5x+8-4\left(-x\right)=-10
Subtract 4\left(-x\right) from both sides.
5x+8-4\left(-1\right)x=-10
Multiply -1 and 4 to get -4.
5x+8+4x=-10
Multiply -4 and -1 to get 4.
9x+8=-10
Combine 5x and 4x to get 9x.
9x=-10-8
Subtract 8 from both sides.
9x=-18
Subtract 8 from -10 to get -18.
x=\frac{-18}{9}
Divide both sides by 9.
x=-2
Divide -18 by 9 to get -2.
