x+4\left(x-2x-14\right)=5\left(1+2\left(x-1\right)\right)
Use the distributive property to multiply -2 by x+7.
x+4\left(-x-14\right)=5\left(1+2\left(x-1\right)\right)
Combine x and -2x to get -x.
x-4x-56=5\left(1+2\left(x-1\right)\right)
Use the distributive property to multiply 4 by -x-14.
-3x-56=5\left(1+2\left(x-1\right)\right)
Combine x and -4x to get -3x.
-3x-56=5\left(1+2x-2\right)
Use the distributive property to multiply 2 by x-1.
-3x-56=5\left(-1+2x\right)
Subtract 2 from 1 to get -1.
-3x-56=-5+10x
Use the distributive property to multiply 5 by -1+2x.
-3x-56-10x=-5
Subtract 10x from both sides.
-13x-56=-5
Combine -3x and -10x to get -13x.
-13x=-5+56
Add 56 to both sides.
-13x=51
Add -5 and 56 to get 51.
x=\frac{51}{-13}
Divide both sides by -13.
x=-\frac{51}{13}
Fraction \frac{51}{-13} can be rewritten as -\frac{51}{13} by extracting the negative sign.
