Just checking if any of you know of any nice WeBWorK problems with applications of systems of three linear equations.I can't seem to locate any from my searches in the OPL, although I may just be missing them.Also any simple problems just asking if an ordered triple is a solution of a given 3 x 3 system?Thanks!Paul
Well - here is two standard coin problems.
The code for each is entirely different; this is discussed in an accompanying pdf document.
The pdf was written to explain what it means for a homework system to be a language as opposed to being just a form that the user fills in to get a problem; the coin problems are discussed here.
Hope this helps
