The reaction is the sum of two reactions.
Here's how to work them out.
1. The hydrobromic acid neutralizes the calcium carbonate in a double replacement reaction. The products are calcium bromide and carbonic acid.
2HBr + CaCO₃ → CaBr₂ + H₂CO₃
2. The carbonic acid is unstable. It decomposes to form carbon dioxide and water.
H₂CO₃ → CO₂ + H₂O
3. The reaction is the sum of the above two equations.
2HBr + CaCO₃ → CaBr₂ + H₂O + CO₂
