Question

the sum of two rational numbers is -5 if one of the number is -13/6 find the other number​

Answer 1

Answer:

$Let \ the \ number \ be = x\\sum \ of \ 2 \ rational \ numbers = -5\\\\x + \frac{-13}{6} = -5\\\\x - \frac{13}{6} = -5$

$x = -5 + \frac{13}{6} = \frac{-30 + 13}{6} = -\frac{17}{6}$

The other rational number = -17/6

Answer 2

Answer:   -17/6

======================================================

Work Shown:

• A = first rational number = -13/6
• B = second rational number = unknown

A+B = -5 ... since the sum of both is -5

B = -5-A

B = -5-(-13/6)

B = -5+13/6

B = -30/6 + 13/6

B = (-30+13)/6

B = -17/6  is the answer
