For the following linear system, put the augmented coefficient matrix into row-echelon form, and then use back substitution to find all solutions. (If the system is inconsistent, enter INCONSISTENT. If there are an infinite number of solutions use t as your parameter.) 2x1 + 8x2 + 3x3 = 2 x1 + 3x2 + 2x3 = 5 2x1 + 7x2 + 4x3 = 8 (x1, x2, x3) =

Step 1
First, we write the augmented matrix for the given system of linear equations: $$ \left[\begin{array}{ccc|c} 2 & 8 & 3 & 0 \\ 1 & 3 & 2 & 5 \\ 2 & 7 & 4 & 0 \end{array}\right] $$ Now, we perform row operations to put the matrix into row-echelon form: Show more…
