3different pairs of numbers that add together to get 1

In order to find different pairs of numbers that adds together to get  you have to follow those steps  

we know that

The linear equation that represent this situation is

------> equation A

where

x and y are the pair of numbers

Step 1

Assume   different values of x and then with the equation find the values of y

so

Step 2

Find the values of y

therefore

the answer is

and

and

and

1. 3

2. 4

3. 1

hope this ! have a great day.
