You can put this solution on YOUR website!
w + s = 10
\n" ); document.write( "s = 10 - w
\n" ); document.write( "12w + 16s = 14(10)
\n" ); document.write( "12w + 16s = 140
\n" ); document.write( "---
\n" ); document.write( "12w + 16(10 - w) = 140
\n" ); document.write( "12w + 160 - 16w = 140
\n" ); document.write( "4w = 20
\n" ); document.write( "---
\n" ); document.write( "w = 5 gal
\n" ); document.write( "s = 5 gal
