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
