1. The problem statement, all variables and given/known data

Calculate the energy released in the alpha neutron reaction for beryllium. The mass of beryllium is 9.012183u.
$$^{4}_{2}$$He + $$^{9}_{4}$$Be $$\rightarrow$$ $$^{1}_{0}$$n + $$^{12}_{6}$$C
2. Relevant equations

3. The attempt at a solution
Tried finding the total binding energy for both side of the equation and then subtracting the right side of the equation from the left.

Could you show us some of your work. Also not sure why you found binding energy, when all you need to find is the mass of each of them to find the difference in total energy.
