If 2x+3 is less than 11 and greater than 1, what is the solution for x?

Answer and explanation

Correct answer: −1<x<4

The governing concept is translating a verbal double condition into a compound inequality and then simplifying all three parts consistently. “2x+3 is greater than 1 and less than 11” becomes 1<2x+3<11. Subtract 3 from every part: −2<2x<8. Divide all parts by the positive number 2, so the inequality directions remain unchanged: −1<x<4. Both endpoints are excluded because the original statements say “greater than” and “less than,” not “at least” or “at most.” Option B incorrectly includes −1, option C incorrectly includes 4, and option D reverses the resulting range. Therefore option A is correct.
