Over the last three evenings, Lisa received a total of 123 phone calls at the call center.
The second evening, she received 4 times as many calls as the third evening.
The first evening, she received 9 fewer calls than the third evening.
How many phone calls did she receive each evening?

First evening + second evening + third evening = 123 phone calls
x-9 + 4x + x = 123
6x - 9 = 123 ====> 6x = 123 + 9 = 132 ====> x = = 22.
