Write a positive and negative integer whose sum is $-$7.

Given: Sum of a positive and a negative integer is $-$7.

To find: Here we have to find a positive and a negative integer whose sum is $-$7.

Solution:

Let the positive integer be = a

Let the negative integer be = b

So, according to the problem:

a $+$ b = $-$7

So, in the above equation we can put value of either a or b to get the corresponding value of other integer:

Example: 

Let positive integer (a) be = 3

So,

3 $+$ b = $-$7

b = $-$7 $-$ 3

b = $-$10

Therefore, 3 and $-$10 is a pair of positive and negative integer whose sum is $-$7.

We can get as many pairs as we want by just changing the values of a and b.
