Cramer's rule gives the solution as $ x = \frac{ \left| \begin{array} { c c } 34 & 5 \\ 37 & 5 \end{array} \right| }{ \left| \begin{array} { c c } 3 & 5 \\ 4 & 5 \end{array} \right| } = 3 $ and $ y = \frac{ \left| \begin{array} { c c } 3 & 34 \\ 4 & 37 \end{array} \right| }{ \left| \begin{array} { c c } 3 & 5 \\ 4 & 5 \end{array} \right| } = 5 $.
