\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.}
