x - Y + -2
can anyone figure this out ?

They are the equations of two straight lines. From your title, it sounds like you're to graph the lines and estimate the solution visually.
Draw a standard XY graph.
Starting with the first equation...
Set X = 0, and solve for Y. Draw a dot on the Y-axis for this point. (I'll give you this one: it's 5).
Then set Y = 0 in the equation, and solve for X. Draw a dot on the X-axis for this point.
Use a ruler to draw the line through these two points.
Repeat for the second linear equation.
The solution is the point where the two lines intersect.
