[tex]\text{ We will graph the two equations}[/tex][tex]\begin{gathered} \text{For that we reexpress the equation in terms of x} \\ 2y=12-x \\ y=-\frac{x}{2}+6 \\ \\ -2y=-12-x \\ y=\frac{x}{2}+6\text{ } \\ \\ \text{Graphing these equations} \end{gathered}[/tex]
And we see that the solution is at (0,6) that is x=0, and y=6
