6x+21-5x+6-8\left(1-2x\right)-\left(x-3\right)=0
Use the distributive property to multiply 3 by 2x+7.
x+21+6-8\left(1-2x\right)-\left(x-3\right)=0
Combine 6x and -5x to get x.
x+27-8\left(1-2x\right)-\left(x-3\right)=0
Add 21 and 6 to get 27.
x+27-8+16x-\left(x-3\right)=0
Use the distributive property to multiply -8 by 1-2x.
x+19+16x-\left(x-3\right)=0
Subtract 8 from 27 to get 19.
17x+19-\left(x-3\right)=0
Combine x and 16x to get 17x.
17x+19-x-\left(-3\right)=0
To find the opposite of x-3, find the opposite of each term.
17x+19-x+3=0
The opposite of -3 is 3.
16x+19+3=0
Combine 17x and -x to get 16x.
16x+22=0
Add 19 and 3 to get 22.
16x=-22
Subtract 22 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-22}{16}
Divide both sides by 16.
x=-\frac{11}{8}
Reduce the fraction \frac{-22}{16} to lowest terms by extracting and canceling out 2.
