Always check your answers before you post them.
from my equation:
x + x+9 + 3x = 89
5x = 80
x = 16
according to my definitions:
first = 25
second = 16
third = 48
Is their sum equal to 89 ? , YES
Do they fit the given conditions ?, YES
Yours do not fit the original conditions
Your first is NOT 9 greater than your second.
