Question

Write down a pair of integer whose (A) sum is -7 (B) difference is -10 (C) sum is 0

Answer 1

A) sum is -7.

Let one integer be -9 and other be +2 .

Then,

-9 + (+2) = -7

Hence,

[ -9 , 2 ]

B) difference is -10

Let one integer be -30 and other be -20.

Then,

-30 - (-20 ) = -30 + 20 = -10

Hence,

[ -30 , -20 ]

C) sum is zero.

Let one integer be 2 and other be -2

Then,

2 + ( -2 ) = 2 - 2 = 0

Hence,

[ 2 , -2 ]

Answer 2

Answer:

sum is -7.

Let one integer be -9 and other be +2 .

Then,

-9 + (+2) = -7

Hence,

[ -9 , 2 ]

B) difference is -10

Let one integer be -30 and other be -20.

Then,

-30 - (-20 ) = -30 + 20 = -10

Hence,

[ -30 , -20 ]

C) sum is zero.

Let one integer be 2 and other be -2

Then,

2 + ( -2 ) = 2 - 2 = 0

Hence,

[ 2 , -2 ]
