\n" ); document.write( "then
\n" ); document.write( "You: 160 + 7w
\n" ); document.write( "Friend: 210 + 5w
\n" ); document.write( ".
\n" ); document.write( "Set them equal to each other and solve for w:
\n" ); document.write( "160 + 7w = 210 + 5w
\n" ); document.write( "160 + 2w = 210
\n" ); document.write( "2w = 50
