T = number of messages Tammy sent
T-7 = number of messages Joe sent
2T = number of messages Austin sent
Tammy + Joe + Austin = 89 total messages
T + (T-7) + (2T) = 89
4T - 7 = 89
4T = 89+7
4T = 96
T = 96/4
T = 24
T-7 = 24-7 = 17
2T = 2*24 = 48
Answers:
Tammy = 24 text messages
Joe = 17 text messages
Austin = 48 text messages
