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