Question 57016
First, solve both equations for y and you get y=-x-3 and y=2x+3.  Plot those out by creating some ordered pairs, draw the lines, and see where they interesect.  The point of intersection is the solution -- in this case, it's (-2,-1).  The graphs of the lines is:
{{{graph(200,200,-5,2,-5,2,-x-3,2x+3)}}}
