-2-3x=2x-1-\left(-x\right)
To find the opposite of 1-x, find the opposite of each term.
-2-3x=2x-1+x
The opposite of -x is x.
-2-3x=3x-1
Combine 2x and x to get 3x.
-2-3x-3x=-1
Subtract 3x from both sides.
-2-6x=-1
Combine -3x and -3x to get -6x.
-6x=-1+2
Add 2 to both sides.
-6x=1
Add -1 and 2 to get 1.
x=\frac{1}{-6}
Divide both sides by -6.
x=-\frac{1}{6}
Fraction \frac{1}{-6} can be rewritten as -\frac{1}{6} by extracting the negative sign.
