Question

Write diwn a pair of integers whose sum is -3,sum is 0,difference is 2,difference is -5

Answer 1

case 1 : for 1st pair

let them b x and y

x+y=-3 => x=-y-3----(1) ;

now , x-y=2 => -y-3-y =2 => -2y=5=> y=-5/2

now by (1) , x=5/2-3=-1 •°•x=-1/2

•°• 1st pair is -1/2 and -5/2

case 2 : for 2nd pair

let them be s and l

x+y=0 =>x=-y ---(1)

now x-y=-5=> -2y=-5=>y=5/2

by (1) x=-5/2

•°• 2nd pair is 5/2 & -5/2

did not understand the ques confidently but tried my best ..hope this helps
