You can put this solution on YOUR website!
x-y= 2 .............1
\n" ); document.write( "2x+2y=4
\n" ); document.write( "/2
\n" ); document.write( "x+y=2 .............2
\n" ); document.write( "
\n" ); document.write( "x-y= 2
\n" ); document.write( "x+y= 2
\n" ); document.write( "
\n" ); document.write( "Add the two equations
\n" ); document.write( "2x=4
\n" ); document.write( "
\n" ); document.write( "/2
\n" ); document.write( "
\n" ); document.write( "x=2
\n" ); document.write( "
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "
\n" ); document.write( "x-y= 2
\n" ); document.write( "2-y= 2
\n" ); document.write( "y=0 \n" ); document.write( "

\n" );
