Question

the sum of two rational no. is -5. if one of them is -11/6 . find other no.

Answer 1

answer is -19/6 as -11/6+x=-5
-11/6+5=-x
-11/6+30/6=-x
19/6=-x
-19/6=x

Answer 2

Let the number be X.
A/Q X + -11/6 = -5
or 6X-11/6 = -5
or 6X-11 = -5×6
or 6X-11 = -30
or 6X = -30+11
or 6X = -19
therefore, X= -19/6
