Question

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

Answer 1

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

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
