Question

I'm currently encountering difficulties in solving this problem and I'm seeking your assistance. The problem specifically requires a solution using matrix form exclusively, without any alternative methods. Could you kindly provide a detailed, step-by-step explanation in matrix form until we arrive at the final solution?

The answer is in photos I can need help doing the matrix way leading me up to that answer

2.4. Consider the system of equations 2x3 + x₂ = 6 x12x₂ + x3 + x₂ = 7 2x₁ + x3 x4 = 2 x12x2x3 + 2x4 = 5. Write down the augmented matrix of the system and row reduce it to echelon form. Identify the free and basic variables. Use back substitution to solve the system of equations.
