Question

write down a pair of integers whose sum is -11 and difference is-19

Answer 1

Let two integers be x and y.

ATQ,

x+y=-11

x=-11-y     .................(i)

Again ATQ,

x-y=-19

from eq (i),x=-11-y

-11-y-y=-19

-11-2y=-19

-11+19=2y

8=2y

8/2=y

4=y

Hence x=-11-y

            =-11-4

            =-15

Thus,pair of integers whose sum is -11 and difference is-19 is -15 and 4

Hope this helps u...
