Given :
Total messages sent = 122
Let the messages sent by Ryan be x
Then, messages sent by Chau be 3x
And, messages sent by Melissa be x + 7
Then, according to question
x + 3x + x + 7 = 122
5x + 7 = 122
5x = 122 - 7
x = 115/5
x = 23
So, messages sent by Ryan = 23
Messages sent by Chau = 3(23)
= 69
Messages sent by Melissa = 23 + 7
= 30
