Can assume that the number of rows at first is 1 unit.

9 units + 6 = 7 units + 84

2 units = 78

1 unit = 39

9 units + 6 = 39 x 9 + 6 = 357

number of rows x 9 ——- (number of rows + 12) x 7 – 6
number of rows ——- (12 x 7 – 6)/(9 – 7) = 39
39 x 9 + 6 = 357
or
(39 + 12) x 7 = 357

Ans : 357 chairs.
