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

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
