You can put this solution on YOUR website!
You have two separate variables and two separate equations here. \r
\n" ); document.write( "\n" ); document.write( "the first one, the sum of two numbers is 35 is set up like x+y=35
\n" ); document.write( "the second one, the difference between the numbers is 13 is set up like x-y=13\r
\n" ); document.write( "\n" ); document.write( "What you need to do is add the second equation to the first equation and solve for x.
\n" ); document.write( "To write it on paper woul look like the x written over the x, y over y etc. \r
\n" ); document.write( "\n" ); document.write( " x+y=35
\n" ); document.write( " x-y=13
\n" ); document.write( "+______\r
\n" ); document.write( "\n" ); document.write( "2x =48 divide both sides by 2\r
\n" ); document.write( "\n" ); document.write( " x=24\r
\n" ); document.write( "\n" ); document.write( "To find y plug the answer for x back into either of the original equations and you will end up with 11.\r
\n" ); document.write( "\n" ); document.write( "Check\r
\n" ); document.write( "\n" ); document.write( "24+11=35
\n" ); document.write( "24-11=13 \n" ); document.write( "

\n" );
