AMC 8 2017 Problem 17

Starting with some gold coins and some empty treasure chests, I tried to put $9$ gold coins in each treasure chest, but that left $2$ treasure chests empty. So instead I put $6$ gold coins in each treasure chest, but then I had $3$ gold coins left over. How many gold coins did I have? $\textbf{(A) }9 \textbf{(B) }27 \textbf{(C) }45 \textbf{(D) }63 \textbf{(E) }81$
