(since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:


Then in this case you turn y=f(x), but the system did it for you, so all you have to put is
.
For the second part you must replace x with 2 since you need to find f(2).

Your answer for part 2 is
.
