what was your answer?

to graph it on your calc, we tend to get y on its own.

\[y _{1}=\frac{ 2.3+0.7x }{ 0.6 }\] \[y _{2}=\frac{ -6.1-0.5x }{ 1.8 }\]

you should get (-5,-2)

You could also use a matrix and apply cramer's rule. and as @chris00 said you should get X = -5 , Y = -2

depends if @Missiey is required to do it. I usually go the most quickest method if the question doesn't tell me to use a specific method
