Question

the sum of two rational numbers is - 8 if one of the numbers is minus 13 by 7 find the other​

Answer 1

Step-by-step explanation:

let x and y be the rational numbers.

x+y = -8

y = -8-x

-13/7 = -8-x

-13 = -56 x

x= 4.30

y= -8-4.30

= -12.30

x+y = -12.30+4.30

= -8

Answer 2

Answer:

let the no be x

given: x+(-13/7) = -8

x = -8+13/7

=[-56+13]/7

= -43/7

-43/7 +(-13/7)

= -56/7

= -8
