Answer is in the picture.
- x + 1 = 3
Solve
1. Subtract 1 from both sides
- x + 1 - 1 = 3 - 1
2. Simplify
a. Subtract the numbers
- x = 3 - 1
b. Subtract the numbers
-x = 3 - 1
- x = 2
3. Divide both sides by the same factor
- x/- 1 = 2/-1
4. Simplify
a. Cancel terms that are in both the numerator and denominator
- x/- 1 = 2/- 1
- x = 2/- 1
b. Divide the numbers
x = 2/-1
x = - 2
