The correct Answer is:
To classify the given system of equations as consistent or inconsistent and solve them if they are consistent, we will follow these steps: ### Step 1: Write the equations in matrix form The given equations are: 1. \(3x - 2y = 4\) 2. \(6x - 4y = 10\) We can express these equations in the form of \(Ax = b\), where: \[ A = \begin{pmatrix} 3 & -2 \\ 6 & -4 \end{pmatrix}, \quad x = \begin{pmatrix} x \\ y \end{pmatrix}, \quad b = \begin{pmatrix} 4 \\ 10 \end{pmatrix} \] ### Step 2: Calculate the determinant of matrix A To determine if the system is consistent or inconsistent, we need to calculate the determinant of matrix \(A\): \[ \text{det}(A) = (3)(-4) - (6)(-2) \] Calculating this gives: \[ \text{det}(A) = -12 + 12 = 0 \] ### Step 3: Analyze the determinant Since the determinant of matrix \(A\) is \(0\), we conclude that the system of equations is inconsistent. This means there are no solutions to the system. ### Final Conclusion The given system of equations is inconsistent. ---
