if 6 zinks = 2 zarks, and 7 zacks = 1 zelk, how many zinks= 2 zelks?

I'm going to assume for this problem that the zarks are the zacks. If they are different, this problem can't be solved.

 

7 zacks = 1 zelk

14 zacks = 2 zelks

2 zacks = 6 zinks

14 zacks = 42 zinks

 

Thus... the answer is \(\color{brown}\boxed{42\space\text zinks}\)

2 * 7 = 14

2 zelks = 14 zacks

14 / 2 * 6

= 7 * 6

= 42

So 14 zacks = 42 zinks
