Hope this helps.

There is nothing to solve for. You stated a constant function, where f(x) will always be 9.

Step-by-step explanation:
I DONT KNOWWWW
Create an equation where x equals extra messages
15 + .05X = 24.60
.05x = 9.60
x=192
So she sent 192 EXTRA messages. Add this to the original 600 and you get 792 messages
The answer is 9.
First subtitute the values into the expression.
x-3y
3-3(-2)
Multiply -3 by -2.
3+6
9
