Using charge balance, we can determine that the charge on the left side of the formula (BaS) is equal to the charge on the right side (OSB14S), which is +4. 
BaS has a charge of +2, while each OSB14S unit has a charge of -4. Therefore, the number of OSB14S units must be 1 (to give a total charge of -4) and the value of x must be 2 (to balance the +2 charge from Ba). Thus, the formula is BaSi2O7S2.
