One month, jerry worked 3 hours less than ben, and chris worked 4 more hours than ben. together they worked 196 hours. find the number of hours each person worked.

65-3=62
65+4=69

Ben worked 65 hrs but jerry worked 3 Less then worked 62 hrs
and Chris 4 hrs more , then worked 69 hrs.

Ben =65 hrs
Jerry =62 hrs
Chris =69 hrs

total = 196 hrs together.
