Answer:
Step-by-step explanation:
3 - x + 1 = 2 combine like terms
-x + (3 + 1) = 2
-x + 4 = 2 subtract 4 from both sides
-x +4 - 4 = 2 - 4
-x = -2 change the signs
x = 2
3 - x + 1 = 2
Add the 3 and the 1
- x + 4 = 2
Subtract the 4 on both sides to isolate the -x
- x + 4 (- 4) = 2 - 4
- x = - 2
Divide both sides by - 1 (to get rid of the negative signs)
