4x-28-2\left(x-8\right)=0
Use the distributive property to multiply 4 by x-7.
4x-28-2x+16=0
Use the distributive property to multiply -2 by x-8.
2x-28+16=0
Combine 4x and -2x to get 2x.
2x-12=0
Add -28 and 16 to get -12.
2x=12
Add 12 to both sides. Anything plus zero gives itself.
x=\frac{12}{2}
Divide both sides by 2.
x=6
Divide 12 by 2 to get 6.
