Question

If sum of two number is 36 and their difference is 10 find two number

Answer 1

the pairs are 23 and 13. those are their pairs

Answer 2

x+y = 36

x-y = 10

Add these two equations to get

2x = 46

x = 23

Sub x=23 into either equation, I like the first.

23 + y = 36

y = 13

23,13 are the pair.
