Question

Write down the pair of integers whose sum is (-4)and difference is (-9)

Answer 1

Answer:

Step-by-step explanation:

Let the integers be x and y

By Given,

x+y= -4 ... 1

x-y= -9

So x= y-9 .....2

Substitute 2 in 1

Therefore

y+y-9=-4

2y=9-4

2y=5

y=5/2

Substitute y in 1

x + 5/2 = -4

x= -4-5/2

x= -13/2

Answer 2

Answer:

none

Step-by-step explanation:

x + y = -4 , x-y = -9

x = -6.5 , y = 2.5

but these are not integers
