# If a and b are integers, and b > 0, does (a - 1)/(b + 1) = a/b

If a and b are integers, and b > 0, does (a - 1)/(b + 1) = a/b?

- a = b - 4
- a = -b

### Answer

(a - 1)/(b + 1) = a/b

ab - b = ab + a

a = -b

You need to determine whether a = -b or not.

**Statement 1:** a = b - 4

From this statement you cannot determine whether a = -b or not. Hence, statement 1 is not sufficient to answer the question.

**Statement 2: **a = -b

Statement 2 is sufficient to answer the question.

**The correct option is B.**
