The answer to the question is to combine like terms first:

-8x - 5 = 4x + 2

Isolate the variable x:

-5 = 12x + 2

12x = -7

x = -7/12

The sum of three numbers is 18. If every number is a prime number, what are the three numbers?
sleet_krkn [62]
The three numbers are 2, 5, and 11.

The sum of 3 numbers is 18.        2 + 5 + 11 = 18

Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.

2 / 1 = 2  OR  2 / 2 = 1  These numbers are prime numbers because their divisors
5 / 1 = 5  OR  5 / 5 = 1            are 1 and itself.
11/1 = 11 OR 11/11 = 1

20 points<br> How on Earth am I supposed to do this
goblinko [34]

Answer: -89

Step-by-step explanation:

So your equation is

- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)

You know that (a) (b) and (c) = -1

You also know that (x) and (y) = 7

So, when you put this into the equation, it will look like this:

- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)

When you work that out you will get left with your answer, which is -89.

HOPE THIS HELPS!!!
