The correct Answer is:
To solve the problem, we need to find the possible values of \( y \) given the conditions \( 1 < x < 4 \) and \( 3x + 2y \leq 13 \). ### Step-by-Step Solution: 1. **Identify the possible values for \( x \)**: Since \( x \) is a positive integer and \( 1 < x < 4 \), the possible values for \( x \) are \( 2 \) and \( 3 \). 2. **Evaluate for \( x = 2 \)**: - Substitute \( x = 2 \) into the inequality: \[ 3(2) + 2y \leq 13 \] - This simplifies to: \[ 6 + 2y \leq 13 \] - Rearranging gives: \[ 2y \leq 7 \] - Dividing by \( 2 \): \[ y \leq 3.5 \] - Since \( y \) must be a positive integer, the possible values for \( y \) are \( 1, 2, 3 \). 3. **Evaluate for \( x = 3 \)**: - Substitute \( x = 3 \) into the inequality: \[ 3(3) + 2y \leq 13 \] - This simplifies to: \[ 9 + 2y \leq 13 \] - Rearranging gives: \[ 2y \leq 4 \] - Dividing by \( 2 \): \[ y \leq 2 \] - Since \( y \) must be a positive integer, the possible values for \( y \) are \( 1, 2 \). 4. **Combine the results**: - From \( x = 2 \), the possible values for \( y \) are \( 1, 2, 3 \). - From \( x = 3 \), the possible values for \( y \) are \( 1, 2 \). - Therefore, the combined possible values for \( y \) are \( 1, 2, 3 \). ### Final Answer: The possible values of \( y \) are \( 1, 2, 3 \).
