Question

3 different pairs of numbers that add together to get 1

Answer 1

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

Answer 2

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 $-29$
