In order to find [tex]3[/tex] different pairs of numbers that adds together to get [tex]1[/tex] you have to follow those steps
we know that
The linear equation that represent this situation is
[tex]x+y=1[/tex]
[tex]y=1-x[/tex] ------> equation A
where
x and y are the pair of numbers
Step 1
Assume [tex]3[/tex] different values of x and then with the equation find the values of y
so
[tex]x1=10\ x2=8\ x3=30[/tex]
Step 2
Find the values of y
[tex]y1=1-10=-9[/tex]
[tex]y2=1-8=-7[/tex]
[tex]y3=1-30=-29[/tex]
therefore
the answer is
[tex]10[/tex] and [tex]-9[/tex]
[tex]8[/tex] and [tex]-7[/tex]
[tex]30[/tex] and [tex]-29[/tex]
