Question

2. Write down a pair of integers whose :
i.Sum is - 6
ii. Difference is - 8
​

Answer 1

Answer:

let the two numbers be X and Y.

X + Y =6 _____________________1

X-Y=8________________________2

add equation 1 and equation 2

2X = 14

X=7

put the value of X in equation 1

7 + Y = 6

Y = -1

Therefore

X=7

Y= (-1)

Answer 2

Answer:

let x and y be two integers

x+y = -6 ____ 1

x-y = -8 _____2

add equation 1 and 2

we get

2x = -14

x = -7

x+y = -6

-7+y = -6

y= -6+7

y=1

so, x= -7 and y=1
