Question

The sum of two integers is$-20$. If one of them is $17$, find the other integer.

Answer 1

Find the other integer:

Given,

The sum of two integers is $-20$

Let take two integers are $X$and $Y$

$\Rightarrow X+Y=-20$

One of them is $17$

So, take $X=17$

$X+Y=-20$

$\Rightarrow 17+Y=-20$

$Y=(-20)+(-17)$ $=-37$

Hence, the other integer is $-37$.
