You can put this solution on YOUR website!
lets say X and Y are the \"numbers\" so it will be\r
\n" ); document.write( "\n" ); document.write( "X+Y=15
\n" ); document.write( "3x-5y=11\r
\n" ); document.write( "\n" ); document.write( "so we know that we can multiply so that you able to cancel out the 3x...so
\n" ); document.write( "we mulitply x+y=15 mulitply it by negative 3 so it can get canceled out.
\n" ); document.write( "so the new equation is -3x-3y=45
\n" ); document.write( "so now you can rewrite it as \r
\n" ); document.write( "\n" ); document.write( "-3x-3y=45
\n" ); document.write( " 3x-5y=11
\n" ); document.write( " -8y=36
\n" ); document.write( "so then
\n" ); document.write( "-8y divided by -8 is just y so then 36/-8 is -4
\n" ); document.write( "so Y=-4
\n" ); document.write( "
\n" ); document.write( "
\n" );
