2x+1+x+2=\frac{1}{1}
Combine x and x to get 2x.
3x+1+2=\frac{1}{1}
Combine 2x and x to get 3x.
3x+3=\frac{1}{1}
Add 1 and 2 to get 3.
3x+3=1
Anything divided by one gives itself.
3x=1-3
Subtract 3 from both sides.
3x=-2
Subtract 3 from 1 to get -2.
x=\frac{-2}{3}
Divide both sides by 3.
x=-\frac{2}{3}
Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.
