This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k
14 is your answer
Explanation:
If he has 16 now because he bought 9. You would do 16 - 9 which equals 7. And if he sold half of his coins that means he has 14.

Answer:
2 5/6
Step-by-step explanation:
9 5/12 - 6 7/12

8 12/12 + 5/12 - 6 7/12
8 17/12 - 6 7/12
(8-6) + (17/12 -7/12)
2 10/12
This simplifies. Divide the top and bottom of the fraction by 2
2 5/6
