In three consecutive small ponds, $A$, $B$, and $C$, several goldfish are placed. If 12 goldfish move from pond $A$ to pond $C$, the number of goldfish in pond $C$ will be twice the number in pond $A$. If 5 goldfish move from pond $B$ to pond $A$, the number of goldfish in pond $A$ will equal the number in pond $B$. Additionally, if 3 goldfish move from pond $B$ to pond $C$, the number of goldfish in pond $B$ will be equal to the number in pond $C$. How many goldfish were originally in pond $A$?
