Use row reduction on the appropriate augmented matrix to solve the following system of equations:

$\begin{array}{ll}3x+2y&=2\\x-y&=1\end{array}

\sim\left[\begin{array}{rr|r}3&2&2\\ \:1&-1&1\end{array}\right]\sim

\begin{bmatrix}1&0&\frac{4}{5}\\ 0&1&-\frac{1}{5}\end{bmatrix}$

$x=\dfrac{4}{5}\quad y= -\dfrac{1}{5}$

hopefully no typos!

suggestions??
