Dear Galeboe:
 
When I interpreted the problem, I interpreted it as
 

(42x) - 1 = (5x) + 2

 
which, of course is quite different from the way Robert interpreted the question, to wit
 

4(2*x-1) = 5(x+2)

 
This is why learning to use parentheses and brackets is so important.  Chances are I was trying to solve the wrong system of equations.
