Question

w write down a pair of integers whose sum
is -4
​

Answer 1

Answer:

8,-12 are those numbers who's sum is -4

Answer 2

Answer:

Infinite number of pairs of integers can be formed which gives the sum $-4$.

Step-by-step explanation:

The pairs of only negative integers whose sum is $-4$ are:

i) $0$ and $-4$, i.e., $0+(-4)=-4$

ii) $-2$ and $-2$, i.e., $-2+(-2)=-4$

iii) $-1$ and $-3$, i.e., $-1+(-3)=-4$

Let pair of integers be $a$ and $b$ such that $a+b=-4$.

⇒ $a=-b-4$ . . . . . (1)

Substitute the value $1$ for $b$ in the equation (1) as follows:

$a=-1-4$

$a=-5$

So, the numbers $-5$ and $1$ is also a pair $of$ integers whose sum is $-4$.

Likewise, substituting the values for $b$ gives the corresponding value for $a$.

Therefore, infinite number of pairs of integers can be found whose sum is $-4$.
