Question

the sum of two rational numbers is -5.If one of the number is -11/6.Find the other​

Answer 1

Let the other number be x

-11/6 + x= -5

x= -5+ 11/6

×= 30/30 + 55/30

x= 85/30

x= 17/6

Answer 2

Let the other be x.

$x + \frac{ - 11}{6} = - 5 \\ \\ \frac{x}{1} + \frac{ - 11}{6} = ( - 5) \\ \\ \frac{6x + ( - 11)}{6} =( - 5) \\ \\ 6x - 11 = - 5 \times 6 \\ \\ 6x - 11 = - 30 \\ \\ 6x = - 30 + 11 \\ \\ x = - \frac{19}{6}$
