You can put this solution on YOUR website!
x+y=6
\n" ); document.write( "x-y=2
\n" ); document.write( "I'm trying to figure out how to solve this for graphing.
\n" ); document.write( "-----------
\n" ); document.write( "Graphing is an \"inexact\" method of solving systems of equations
\n" ); document.write( "because the accuracy of the solution depends completly on the
\n" ); document.write( "accuracy of the graph--and most of us are not very accurate is
\n" ); document.write( "drawing graphs.
\n" ); document.write( "So you do the best you can.
\n" ); document.write( "You graph the two lines and try to determine their point of
\n" ); document.write( "intersection.
\n" ); document.write( "--------
\n" ); document.write( "If you add your two equations you get 2x=8; x=4.
\n" ); document.write( "Substituting will also give you y = 2
\n" ); document.write( "That information is helpful when you come to determining the
\n" ); document.write( "point of intersection.
