You can put this solution on YOUR website!
Solve the 1st equation for \"Y\" as follows:
\n" ); document.write( "Y = X-3. Now plot a couple of points, like
\n" ); document.write( "(0,-3) and (3,0) and draw the line.
\n" ); document.write( "Then solve the 2nd equation for Y as follows:
\n" ); document.write( "Y = -X+1. Plot a couple of points for this
\n" ); document.write( "equation, such as ((0,1) and (1,0), and draw
\n" ); document.write( "that line.
\n" ); document.write( "Find the point where the two lines meet. The
\n" ); document.write( "X and Y value of that point give you the solution.\r
