The sum of two numbers is - 16 One number is seven times the other find the numbers

The answer is - 2 + (-14) = - 16

Step-by-step explanation:

Let a = first number or the number is seven times "the other"

Let b = second number or "the other"

We have

a + b = - 16

a = 7b

So we subtitie a = 7b to a + b = - 16 which generate:

7b + b = - 16

8b = - 16

b = - 2

We know the other number is - 2, we need to find the second number

a = 7b

a = 7 (-2)

a = - 14

Thus the numbers are - 2 and - 14
