Verified Answer :

3 different pairs are...
0+1=1
-1+2=1
-2+3=1

In order to find \(3\) different pairs of numbers that adds together to get \(1\)  you have to follow those steps  

we know that

The linear equation that represent this situation is

\(x+y=1\)

\(y=1-x\) ------> equation A

where

x and y are the pair of numbers

Step 1

Assume  \(3\) different values of x and then with the equation find the values of y

so

\(x1=10\ x2=8\ x3=30\)

Step 2

Find the values of y

\(y1=1-10=-9\)

\(y2=1-8=-7\)

\(y3=1-30=-29\)

therefore

the answer is

\(10\) and \(-9\)

\(8\) and \(-7\)

\(30\) and \(-29\)
