To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 2 c_3 = 1 c_4 = 3 c_5 = 2 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | CH_3CHO + 2 Ag(NH3)2OH ⟶ H_2O + 3 NH_3 + 2 Ag + CH_3CO_2NH_4
