4-\left(2-\left(2x-1-\left(-x\right)+1\right)\right)=4x-1
To find the opposite of 1-x, find the opposite of each term.
4-\left(2-\left(2x-1+x+1\right)\right)=4x-1
The opposite of -x is x.
4-\left(2-\left(3x-1+1\right)\right)=4x-1
Combine 2x and x to get 3x.
4-\left(2-3x\right)=4x-1
Add -1 and 1 to get 0.
4-2-\left(-3x\right)=4x-1
To find the opposite of 2-3x, find the opposite of each term.
4-2+3x=4x-1
The opposite of -3x is 3x.
2+3x=4x-1
Subtract 2 from 4 to get 2.
2+3x-4x=-1
Subtract 4x from both sides.
2-x=-1
Combine 3x and -4x to get -x.
-x=-1-2
Subtract 2 from both sides.
-x=-3
Subtract 2 from -1 to get -3.
x=3
Multiply both sides by -1.
