You can put this solution on YOUR website!

\n" ); document.write( "X+Y=9---------------------------Equation #1
\n" ); document.write( "X-Y=3----------------------------Equation #2\r
\n" ); document.write( "\n" ); document.write( "First we will add Eq1 and Eq2 and we get\r
\n" ); document.write( "\n" ); document.write( "X+X+Y-Y=9+3 collect like terms\r
\n" ); document.write( "\n" ); document.write( "2X=12 divide both sides by 2
\n" ); document.write( "X=6 substitute 6 for X in Eq1 and we get:\r
\n" ); document.write( "\n" ); document.write( "6+Y=9 subtract 6 from both sides
\n" ); document.write( "6-6+Y=9-6 collect like terms\r
\n" ); document.write( "\n" ); document.write( "Y=3\r
\n" ); document.write( "\n" ); document.write( "So are answer is:\r
\n" ); document.write( "\n" ); document.write( "X=6, Y=3\r
\n" ); document.write( "\n" ); document.write( "CK\r
\n" ); document.write( "\n" ); document.write( "Substitute the values of X and Y into eq 1
\n" ); document.write( "6+3=9
\n" ); document.write( "9=9
\n" ); document.write( "Now substitute the values of X and Y into eq 2
\n" ); document.write( "6-3=3
\n" ); document.write( "3=3\r
\n" ); document.write( "\n" ); document.write( "Hope this helps----ptaylor\r
