Question
In Problems 37-72, solve each system of equations using malrices (row operations). If the system has no solution, say that it is inconsistent. $\left\{\begin{array}{l}x+y=8 \\ x-y=4\end{array}\right.$
Step 1
The given system is: \[ x + y = 8 \] \[ x - y = 4 \] This can be represented as: \[ \begin{bmatrix} 1 & 1 \\ 1 & -1 \end{bmatrix} \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 8 \\ 4 \end{bmatrix} \] Show more…
