The correct Answer is:
To determine if the pair \( (x, y) = (2, 3) \) is a solution to the given linear equations, we will substitute \( x = 2 \) and \( y = 3 \) into each equation and check if both sides are equal. ### Step-by-Step Solution: 1. **Equation 1: \( 2x + y = 8 \)** - Substitute \( x = 2 \) and \( y = 3 \): \[ 2(2) + 3 = 4 + 3 = 7 \] - Compare with the right-hand side: \[ 7 \neq 8 \] - Conclusion: \( (2, 3) \) is **not** a solution for this equation. 2. **Equation 2: \( x + 2y = 8 \)** - Substitute \( x = 2 \) and \( y = 3 \): \[ 2 + 2(3) = 2 + 6 = 8 \] - Compare with the right-hand side: \[ 8 = 8 \] - Conclusion: \( (2, 3) \) **is** a solution for this equation. 3. **Equation 3: \( x + y = 8 \)** - Substitute \( x = 2 \) and \( y = 3 \): \[ 2 + 3 = 5 \] - Compare with the right-hand side: \[ 5 \neq 8 \] - Conclusion: \( (2, 3) \) is **not** a solution for this equation. 4. **Equation 4: \( -2x + y = 1 \)** - Substitute \( x = 2 \) and \( y = 3 \): \[ -2(2) + 3 = -4 + 3 = -1 \] - Compare with the right-hand side: \[ -1 \neq 1 \] - Conclusion: \( (2, 3) \) is **not** a solution for this equation. ### Final Conclusion: The pair \( (x, y) = (2, 3) \) is a solution for the equation \( x + 2y = 8 \). ---
