Ankor failed to correctly algebraically define the word problem, and also failed to do correct math.\r

\n" ); document.write( "\n" ); document.write( "HypatiaLeigh is correct - Fish is 72\" long.\r
\n" ); document.write( "\n" ); document.write( "Using the same solve/substitute methods, we got the same answer when instead first solving for Body (as opposed to Hypatia starting solve for tail first).\r
