106-\left(4+x\right)\left(3x-1\right)=\left(x-4\right)\left(2x-1\right)+\left(x-4\right)\left(x+4\right)\left(-5\right)
Variable x cannot be equal to any of the values -4,4 since division by zero is not defined. Multiply both sides of the equation by \left(x-4\right)\left(x+4\right), the least common multiple of x^{2}-16,4-x,x+4.
106+\left(-4-x\right)\left(3x-1\right)=\left(x-4\right)\left(2x-1\right)+\left(x-4\right)\left(x+4\right)\left(-5\right)
Use the distributive property to multiply -1 by 4+x.
106-11x+4-3x^{2}=\left(x-4\right)\left(2x-1\right)+\left(x-4\right)\left(x+4\right)\left(-5\right)
Use the distributive property to multiply -4-x by 3x-1 and combine like terms.
110-11x-3x^{2}=\left(x-4\right)\left(2x-1\right)+\left(x-4\right)\left(x+4\right)\left(-5\right)
Add 106 and 4 to get 110.
110-11x-3x^{2}=2x^{2}-9x+4+\left(x-4\right)\left(x+4\right)\left(-5\right)
Use the distributive property to multiply x-4 by 2x-1 and combine like terms.
110-11x-3x^{2}=2x^{2}-9x+4+\left(x^{2}-16\right)\left(-5\right)
Use the distributive property to multiply x-4 by x+4 and combine like terms.
110-11x-3x^{2}=2x^{2}-9x+4-5x^{2}+80
Use the distributive property to multiply x^{2}-16 by -5.
110-11x-3x^{2}=-3x^{2}-9x+4+80
Combine 2x^{2} and -5x^{2} to get -3x^{2}.
110-11x-3x^{2}=-3x^{2}-9x+84
Add 4 and 80 to get 84.
110-11x-3x^{2}+3x^{2}=-9x+84
Add 3x^{2} to both sides.
110-11x=-9x+84
Combine -3x^{2} and 3x^{2} to get 0.
110-11x+9x=84
Add 9x to both sides.
110-2x=84
Combine -11x and 9x to get -2x.
-2x=84-110
Subtract 110 from both sides.
-2x=-26
Subtract 110 from 84 to get -26.
x=\frac{-26}{-2}
Divide both sides by -2.
x=13
Divide -26 by -2 to get 13.
