# Coins

Denis and Zdeno together have 97 coins. If Denis had 4 coins less than he has now, the number of the coins would be in the ratio 14: 17. Determine the number of coins owned by Denis and Zdeno.

Result

D =  46
Z =  51

#### Solution:

D+Z=97
D-4=14:17*Z

D+Z = 97
D-0.823529Z = 4

D = 46
Z = 51
