Answer 3

To solve the inequality -12 < 2(x + 3) < 4, we need to simplify and isolate the variable x.

Let's break it down step by step:

-12 < 2(x + 3) < 4

First, we can divide the entire inequality by 2 to simplify it:

-6 < x + 3 < 2

Next, we can subtract 3 from all parts of the inequality:

-6 - 3 < x + 3 - 3 < 2 - 3

Simplifying further:

-9 < x < -1

Therefore, the solution to the inequality is -9 < x < -1.
