Question

Find a pair of negetive integers x and y such that
1. x-y=5
2.y-x=-4​

Answer 1

Answer:

1. x = -1 y = -6

2. x = -10 y = -4

Answer 2

Answer:

As given x and y are two non-negative integral numbers such that 2x+y=10.

So, the possible values will be (0,10),(1,8),(2,6),(3,4),(4,2),(5,0)

The maximum value of x+y=10 and minimum value of x+y=5.

∴ sum of maximum and minimum value of x+y is 15.
