## Text Solution

**What is known?**

Sum and difference of a pair of integers.

**What is the unknown?**

The two integers whose sum is given.

**Reasoning:**

Add or subtract the two values.

**Steps:**

a) sum is \(-7\)

Let us take a pair of integer \(-8\) and \(+1 \)

\[\begin{align}&={- 8}{+1}\\&=-7\end{align}\]

b) difference is \(-10 \)

Let us take a pair of integer \(-12\) and \(-2 \)

\[\begin{align}&={- 12\,- }{(-2)}\\&=-10\end{align}\]

c) sum is \(0\)

Let us take a pair of integer \(-5\) and \(+5\)

\[\begin{align}&={5\,+ }{(-5)}\\&=0\end{align}\]
