Answer:
Step-by-step explanation:
Let x represent the number of hours that he worked in the second week.
He worked 5 hours more during the second week than the first week. This means that the number of hours that he worked in the first week is x - 5
The third week, he worked 2 hours less than the second week. This means that the number of hours that he worked in the third week is x - 2
Ted worked a total of 50 hours over the last 3 weeks. This means that
x - 5 + x + x - 2 = 50
3x - 7 = 50
3x = 50 + 7 = 57
x = 57/3 = 19
The number of hours that he worked in the first week is
19 - 5 = 14 hours
The number of hours that he worked in the third week is
19 - 2 = 17 hours
