Answer:
11
Step-by-step explanation:
The number of numbers whose average is 7 is (n-6), so the overall equation for the average of the numbers in the set is ...
(7(n-6) +6(29))/n = 19
7n +132 = 19n . . . . multiply by n, collect terms
132 = 12n . . . . . . . . subtract 7n
11 = n . . . . . . . . . . . divide by 12
The value of n is 11.
