Kaden and Dave bought some stamps and shared them equally between themselves. Mother then gave 1 stamp to Kaden and 9 stamps to Dave. As a result, Kaden had 3/5 as many stamps as Dave. How many stamps did Kaden and Dave buy altogether?

Answer: 22 stamps altogether

Explanation: k+1 = 3/5 (d+9)

5k+5 = 3d+27

5k-3d = 22

But, since k=d,

2k = 22

k=11

so they started out with 11 stamps each, or 22 altogether
