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. $\left\{\begin{array}{c}\frac{1}{2} x+y=-2 \\ x-2 y=8\end{array}\right.$
Step 1
The given system is: \[ \left\{ \begin{array}{c} \frac{1}{2} x + y = -2 \\ x - 2y = 8 \end{array} \right. \] Multiply the first equation by 2 to eliminate the fraction: \[ x + 2y = -4 \] Show more…
