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.
