Answer 6

You remember what I said before? Pretend x + 2 < -5 is an equation.
So it would magically become x + 2 = -5
To find x, you want to get rid of 2. To get rid of 2, you want to subtract both side by 2.
2-2 = 0 (Cancel out)
-5 - 2 = -7. How? Well, you have a negative number. Since you're subtracting it by a negative number, you're moving the number to the right. (More to the negative side) Here's how it looks like in a line: Make sense? Alright, your equation should look like:
x < - 7 OR -7 > x

I hope this help!
