I would solve it using matrices, thus obtaining the answer (x,y)=(-1,8). When you draw a graph the two graphs should intersect at thia point

For this case, we observe the attached figure. We have the following system of two equations with two unknowns:

[tex]x + y = -7\\2x + y = 6[/tex]

The solution of the system will be given by the intersection of the lines. That is, the solution is:

[tex](x, y) = (13, -20)[/tex]

Answer:

See attached figure

[tex](x, y) = (13, -20)[/tex]
