You can put this solution on YOUR website!
From the two given equations,
\n" ); document.write( "\"%282%5E4%29%5Ex+%2A%282%5E2%29%5Ey=2%5E6\"
\n" ); document.write( "\"2%5E%284x%2B4y%29=2%5E6\"
\n" ); document.write( "\"highlight%284x%2B4y=6%29\"
\n" ); document.write( "and
\n" ); document.write( "\"%285%5E2%29%5Ex%2F%285%5E3%29%5Ey=5%5E%281%2F2%29\"
\n" ); document.write( "\"5%5E%282x-3y%29=5%5E%281%2F2%29\"
\n" ); document.write( "\"highlight%282x-3y=1%2F2%29\"
\n" ); document.write( "-
\n" ); document.write( "-
\n" ); document.write( "Your system to solve is then this:
\n" ); document.write( "\"4x%2B4y=6\" and \"2x-3y=1%2F2\"
\n" ); document.write( "Simplification gives you:
\n" ); document.write( "---------------------------------------
\n" ); document.write( "\"highlight%282x%2B2y=3%29\" and \"highlight%284x-6y=1%29\"
\n" ); document.write( "---------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You should now find this system easier to handle.
\n" ); document.write( "
\n" );
