x-2-2x+2=x+1-\left(x-4\right)
Use the distributive property to multiply -2 by x-1.
-x-2+2=x+1-\left(x-4\right)
Combine x and -2x to get -x.
-x=x+1-\left(x-4\right)
Add -2 and 2 to get 0.
-x=x+1-x-\left(-4\right)
To find the opposite of x-4, find the opposite of each term.
-x=x+1-x+4
The opposite of -4 is 4.
-x=1+4
Combine x and -x to get 0.
-x=5
Add 1 and 4 to get 5.
x=-5
Multiply both sides by -1.
