\n" ); document.write( "I used GeoGebra to graph this.\r

\n" ); document.write( "\n" ); document.write( "The two lines cross at (x,y) = (3,2) which is the solution to the system.
\n" ); document.write( "Plug those coordinates back into the original equations and simplify.
\n" ); document.write( "You should get the same thing on both sides to verify the solution.
