Answer:
6 seats in the other 7 rows.
Step-by-step explanation:
7x + y = 50 where y is the number of seats in the front row and x is the number in the last 7 rows.. We have to fit whole numbers to x and y to make a total of 50.
x cannot be 7 as 7*7 is 49 which only leaves 1 for the front row.
Try x = 6:-
7*6 = 42 which leaves 8 seats in the front row.
