Answer 2

$\sf \bf {\boxed {\mathbb {GIVEN:}}}$

Sum of the two numbers = $-5$

One of the number = $3$

$\sf \bf {\boxed {\mathbb {TO\:FIND:}}}$

The other number.

$\sf \bf {\boxed {\mathbb {SOLUTION:}}}$

The other number is $\sf\blue{-8}$.

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:\:EXPLANATION:}}}$

Let the other number be $x$.

As per the question, we have

$Sum \: \: of \: \: the \: \: two \: \: numbers = -5$

$➺ \: 3 + x = - 5$

$➺ \: x = - 5 - 3$

$➺ \: x = - 8$

$\sf\purple{Therefore,\:the\:other\:number\:is\:-8.}$

$\sf \bf {\boxed {\mathbb {TO\:VERIFY :}}}$

$➪ \: 3 + ( - 8) = - 5$

$➪ \: 3 - 8 = - 5$

$➪ \: - 5 = - 5$

➪ L. H. S. = R. H. S.

$\sf\orange{Hence\:verified.}$
