-2-\left(-x\right)-\left(x-\left(3x-1\right)\right)=2-x
To find the opposite of 2-x, find the opposite of each term.
-2+x-\left(x-\left(3x-1\right)\right)=2-x
The opposite of -x is x.
-2+x-\left(x-3x-\left(-1\right)\right)=2-x
To find the opposite of 3x-1, find the opposite of each term.
-2+x-\left(x-3x+1\right)=2-x
The opposite of -1 is 1.
-2+x-\left(-2x+1\right)=2-x
Combine x and -3x to get -2x.
-2+x-\left(-2x\right)-1=2-x
To find the opposite of -2x+1, find the opposite of each term.
-2+x+2x-1=2-x
The opposite of -2x is 2x.
-2+3x-1=2-x
Combine x and 2x to get 3x.
-3+3x=2-x
Subtract 1 from -2 to get -3.
-3+3x+x=2
Add x to both sides.
-3+4x=2
Combine 3x and x to get 4x.
4x=2+3
Add 3 to both sides.
4x=5
Add 2 and 3 to get 5.
x=\frac{5}{4}
Divide both sides by 4.
