Question

Solve the inequality.

|r + 3| ≥ 7

Answer 1

1. First do this step (it is not a legal step) but it helps to see which way to place the inequalities

-7 ≥ r + 3 ≥ 7

2. Next re-write as two inequalities as follows:

r + 3 ≥ 7
r + 3 ≤ -7

Now solve each inequality:

r ≥ 7 - 3
r ≤ -7 - 3

r ≥ 4
r ≤ -10

Answer 2

notice how quiet i am...

Answer 3

I notice. You hate my first step.
