The sum of a number in and eight is multiplied by -4 and the result is -12. What is the number of N?

1 answer

Let's represent the number as N.

According to the given information, the sum of N and 8 can be represented as (N + 8).

The next part of the problem states that this sum is multiplied by -4 and the result is -12:

-4(N + 8) = -12

Now, let's solve for N:

-4N - 32 = -12
-4N = -12 + 32
-4N = 20
N = 20 / -4
N = -5

Therefore, the number N is -5.
