Beyond the Answer
When you subtract the second equation \(3x + 2y = -5\) from the first equation \(3x - 4y = 7\), you combine the equations as follows: 1. Start with the two equations: \[ 3x - 4y = 7 \quad (1) \] \[ 3x + 2y = -5 \quad (2) \] 2. Now, perform the subtraction: \[ (3x - 4y) - (3x + 2y) = 7 - (-5) \] 3. This simplifies to: \[ 3x - 4y - 3x - 2y = 7 + 5 \] \[ -6y = 12 \] So, the correct result is: \(-6y = 12\).
