Question

The sum of two rational is -8. If one of the numbers is −15/7, find the other.

Answer 1

Answer:

-41/7.

Step-by-step explanation:

Let the number be x.

-15/7 + x = -8

x = -8 + 15/7

x = -8x7/1x7 + 15/7

x = -56/7 + 15/7

x= -41/7.

Hope this helped you :)

Answer 2

Step-by-step explanation:

Let the other number be x

x+(-15/7)=-8

x-15/7=-8

7x-15/7=-8

7x-15=-8*7

7x-15=-56

7x=-56+15

7x=-41

x=-41/7

So the other number is -41/7 ans
