Consider the following system of linear equations. 4x + 12y = 32 -3x - 14y = 14 Solve the system by completing the steps below to produce a reduced row-echelon form. $R_1$ and $R_2$ denote the first and second rows, respectively. The arrow notation ($\rightarrow$) means the expression/matrix on the left becomes the expression/matrix on the right once the row operations are performed. (a) Enter the augmented matrix. (b) For each step below, enter the coefficient for the row operation and the missing entries in the resulting matrix. Step 1: $\Box R_1 \rightarrow R_1$ Step 2: $\Box R_1 + R_2 \rightarrow R_2$ Step 3: $\Box R_2 \rightarrow R_2$
