8+12x-\left(4-x\right)+1-2x=1
Use the distributive property to multiply 2+3x by 4.
8+12x-4-\left(-x\right)+1-2x=1
To find the opposite of 4-x, find the opposite of each term.
8+12x-4+x+1-2x=1
The opposite of -x is x.
4+12x+x+1-2x=1
Subtract 4 from 8 to get 4.
4+13x+1-2x=1
Combine 12x and x to get 13x.
5+13x-2x=1
Add 4 and 1 to get 5.
5+11x=1
Combine 13x and -2x to get 11x.
11x=1-5
Subtract 5 from both sides.
11x=-4
Subtract 5 from 1 to get -4.
x=\frac{-4}{11}
Divide both sides by 11.
x=-\frac{4}{11}
Fraction \frac{-4}{11} can be rewritten as -\frac{4}{11} by extracting the negative sign.
