This is an inequality equation. It is not equal to a specific number. There are a lot of numbers that can be considered as long as it makes the inequality equation TRUE.

b - 2 > -1
+ 2 + 2
b > 1

b is a number that is at least 1 or greater than 1.

b = 1

1 - 2 > -1
- 1 > -1 True. Had the sign been only > and not >, 1 would not be a value of b.

b = 2
2 - 2 > -1
0 > -1 True.
