The balanced reaction is as below
3A2B +2DC3 → 6 AC + D2B3
Explanation
According to the law of mass conservation the number of atoms in the reactant side must be equal to number of atoms in product side.
putting coefficient 3 in front of A2B, 2 in front DC3 and 6 in front of AC balance the equation , since the number of atoms is equal in both side.
for example we have 3 atoms of A in both reactant and products side.
