\n" );
document.write( "by adding...we find the point the two lines may have in common.
\n" );
document.write( "4x+y= 7 
\n" );
document.write( " x-y=-2
\n" );
document.write( "5x = 5
\n" );
document.write( " x = 1  
\n" );
document.write( "4x+y= 7 
\n" );
document.write( "4*1+y= 7 
\n" );
document.write( "   y = 3
