To transform the given matrix into echelon form, we will perform a series of elementary row operations. The given matrix is: 1 & 0 & 3 & 0 \\ 5 & 4 & 2 & 2 \\ 2 & 5 & 1 & 0 \\ 3 & 7 & 5 & 2 Step 1: Make the entries below the leading 1 in the first column zero. Perform the following row operations: R_2 R_2 - 5R_1 R_3 R_3 - 2R_1 R_4 R_4 - 3R_1 Calculations for the new rows: R_2: [5, 4, 2, 2] - 5[1, 0, 3, 0] = [5-5, 4-0, 2-15, 2-0] = [0, 4, -13, 2] R_3: [2, 5, 1, 0] - 2[1, 0, 3, 0] = [2-2, 5-0, 1-6, 0-0] = [0, 5, -5, 0] R_4: [3, 7, 5, 2] - 3[1, 0, 3, 0] = [3-3, 7-0, 5-9, 2-0] = [0, 7, -4, 2] The matrix becomes: 1 & 0 & 3 & 0 \\ 0 & 4 & -13 & 2 \\ 0 & 5 & -5 & 0 \\ 0 & 7 & -4 &
