Given:
Total number of calls over the last three evenings = 62 phone calls
Let the number of calls received on the second evening = x
The third evening she received 2 times as many calls as the second evening.
So, the number of calls on the third evening = 2x
The first evening she received 6 fewer cells than the second evening
So, the number of calls on the first evening = x - 6
So, as the total calls = 62

Solve for x:

So, the answer will be:
The number of calls on the first evening = x - 6 = 11 calls
The number of call on the second evening = x = 17 calls
The number of calls on the third evening = 2x = 34 calls
