Answer: Alonzo sent 15 messages
Kala sent 22 messages
Bill send 60 messages
Step-by-step explanation:
Let x represent the number of messages that Alonso sent during the weekend.
Bill sent 4 times as many messages as alonzo. It means that the number of messages Bill sent is 4x.
Kala sent 7 more messages than alonzo. It means that the number of messages Kala sent is x + 7
Kala, bill alonzo sent a total of 97 text messages during the weekend.
It means that
x + 4x + x + 7 = 97
6x + 7 = 97
6x = 97 - 7 = 90
x = 90/6
x = 15
The number of messages that Bill sent is
4 × 15 = 60
The number of messages that Kala sent is
15 + 7 = 22
