2-x-\left(-1\right)-\left(x-1\right)=3+x
To find the opposite of x-1, find the opposite of each term.
2-x+1-\left(x-1\right)=3+x
The opposite of -1 is 1.
3-x-\left(x-1\right)=3+x
Add 2 and 1 to get 3.
3-x-x-\left(-1\right)=3+x
To find the opposite of x-1, find the opposite of each term.
3-x-x+1=3+x
The opposite of -1 is 1.
3-2x+1=3+x
Combine -x and -x to get -2x.
4-2x=3+x
Add 3 and 1 to get 4.
4-2x-x=3
Subtract x from both sides.
4-3x=3
Combine -2x and -x to get -3x.
-3x=3-4
Subtract 4 from both sides.
-3x=-1
Subtract 4 from 3 to get -1.
x=\frac{-1}{-3}
Divide both sides by -3.
x=\frac{1}{3}
Fraction \frac{-1}{-3} can be simplified to \frac{1}{3} by removing the negative sign from both the numerator and the denominator.
