On the first evening Jamie received 13 calls.
Step-by-step explanation:
Total number of phone calls received by Jamie over three evenings = 123
Let the number of phone calls received on the third evening = x.
The number of phone calls received on the second evening = 4*x.
The number of phone calls received on the first evening = 
Expressing in equation form:
![\[x+4x+x-9=123\]](https://tex.z-dn.net/?f=%5C%5Bx%2B4x%2Bx-9%3D123%5C%5D)
![\[=>6x-9=123\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E6x-9%3D123%5C%5D)
![\[=>6x=132\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E6x%3D132%5C%5D)
![\[=>x=\frac{132}{6}\]](https://tex.z-dn.net/?f=%5C%5B%3D%3Ex%3D%5Cfrac%7B132%7D%7B6%7D%5C%5D)
![\[=>x=22\]](https://tex.z-dn.net/?f=%5C%5B%3D%3Ex%3D22%5C%5D)
So Jamie received 22 calls on the third evening, 88 calls on the second evening and 13 calls on the third evening.
