2s = sunflowers
\n" ); document.write( "3r = raisins
\n" ); document.write( "2s + 3r = 2900
\n" ); document.write( "r = s-400
\n" ); document.write( "--------------------
\n" ); document.write( "now replace what r = with r in the other equation;\r
\n" ); document.write( "\n" ); document.write( "2s + 3(s-400) = 2900
\n" ); document.write( "2s + 3s - 1200 = 2900
\n" ); document.write( "Collect like terms and add 1200 to both sides;
\n" ); document.write( "5s = 4100
\n" ); document.write( "divide by 5;
\n" ); document.write( "s = 820
\n" ); document.write( "Now we have s, lets find r;
\n" ); document.write( "2(820) + 3r = 2900
\n" ); document.write( "1640 + 3r = 2900
\n" ); document.write( "3r = 1260
\n" ); document.write( "r = 420
\n" ); document.write( ":)
\n" ); document.write( "
\n" ); document.write( "
\n" );
