Answer by sudhanshu_kmr(1152)   (Show Source): You can put this solution on YOUR website!

here z = 0
17z = 7z
=> 17z - 7z = 0
=> 10z = 0
it is possible if and only if z = 0

17z = 7z

The z is even a hint at the solution.  The solution
when spelled out, begins with the letter z.  Can you
think of a number that when spelled, starts with a z?
I'll bet you can. 

Try subtracting 7z from both sides of the eqution.  Then
divide both sides by 7.  I think you can get the solution.
Remember it starts with a z.

Oh shux.  The other two tutors gave it away before I could post this!
