Solve the system of equations.
\n" ); document.write( "Do this by the addition method -- add both equations together:
\n" ); document.write( "4x-y=6
\n" ); document.write( " x+y=4
\n" ); document.write( "-------
\n" ); document.write( "5x =10
\n" ); document.write( "x = 2
\n" ); document.write( ".
\n" ); document.write( "Substitute the above into:
\n" ); document.write( " x+y=4
\n" ); document.write( " 2+y=4
\n" ); document.write( " y=2
\n" ); document.write( ".
\n" ); document.write( "Therefore, the graphs cross at:
\n" ); document.write( "(x,y) = (2,2)
\n" ); document.write( "
\n" ); document.write( "
\n" );
