Just checking if any of you know of any nice WeBWorK problems withapplicationsofsystemsofthreelinear 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

### Re: Applications of Systems of Three Linear Equations

by Hedley Pinsent -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

Thank you, Hedley!

I'll try these two problems out. They will make a good starting point for a few more I will try to create.
