The correct Answer is:
To solve the system of equations: 1. **Write down the equations:** \[ 3x + 2y = 11 \quad \text{(Equation 1)} \] \[ 2x + 3y = 4 \quad \text{(Equation 2)} \] 2. **Multiply the equations to align coefficients for elimination:** - Multiply Equation 1 by 3: \[ 3(3x + 2y) = 3(11) \implies 9x + 6y = 33 \quad \text{(Equation 3)} \] - Multiply Equation 2 by 2: \[ 2(2x + 3y) = 2(4) \implies 4x + 6y = 8 \quad \text{(Equation 4)} \] 3. **Subtract Equation 4 from Equation 3 to eliminate \(y\):** \[ (9x + 6y) - (4x + 6y) = 33 - 8 \] This simplifies to: \[ 5x = 25 \] 4. **Solve for \(x\):** \[ x = \frac{25}{5} = 5 \] 5. **Substitute \(x\) back into one of the original equations to find \(y\):** - Substitute \(x = 5\) into Equation 1: \[ 3(5) + 2y = 11 \] This simplifies to: \[ 15 + 2y = 11 \] \[ 2y = 11 - 15 \] \[ 2y = -4 \] \[ y = \frac{-4}{2} = -2 \] 6. **Final solution:** The values of \(x\) and \(y\) are: \[ x = 5, \quad y = -2 \]
