This is a double inequality. Let's take it by pieces: Three more than 2x is denoted as 2x + 3. We add since we see the phrase, more than. Because it's greater than or equal to 1, we have: 1 <= 2x + 3 Finally, that same phrase is also less than or equal to 11. 2x + 3 <= 11. Piecing these two inequalities together, we have: 1 <= 2x + 3 <= 11.
