Question 1100355
<pre>
Apparently the younger generation doesn't see any need for punctuation marks or
capital letters to separate sentences.  They just run them all together. And
soon the correct way to write will include "u" for "you", "r" for "are",
"before" as "b4", "8" for "ate", etc.  

In that light, there are plenty of sites online where you only have to type in a
system of equations, point and click, and the answer pops out instantaneously.
So why not use them?   You can even do it on a TI-84 calculator, if you install
the right program.  Why hitch a horse to a buggy and get there in an hour, when
you can drive a car and get there in 10 minutes? 

If you use a separate letter for each unknown, setting up the equations is a
cinch. This system below is set up directly from the words:

{{{system(25q+10d+5n=315,q=(1/2)(d+n),n=d+2)}}}

Go to one of those sites. Type that in. Point and click, and instantly you 
get q=8, d=7, n=9.  Here is a link to such a site:
