Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: 
Let's use the points (1, 27) and (2, 39) in the expression:

Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)

Answer:
x = 1
Step-by-step explanation:
Expand brackets
2x + 16 - 4x = 10x + 4
Rearrange so that x's are on one side and whole numbers are on the other
2x - 4x - 10x = 4 - 16
Simplify
-12x = -12
Make x on its own
x = 1
