need help solving this problem

Answer:
Part 1: [tex]\frac{11-x}{5}[/tex] or [tex]\frac{11}{5}-\frac{x}{5}[/tex]
Part 2: [tex]\frac{9}{5}[/tex]
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get [tex]5y=11-x[/tex] (since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:
[tex]\frac{5y}{5} =\frac{11}{5}-\frac{x}{5}[/tex]
[tex]y=\frac{11}{5}-\frac{x}{5}[/tex]
Then in this case you turn y=f(x), but the system did it for you, so all you have to put is [tex]\frac{11}{5}-\frac{x}{5}[/tex].
For the second part you must replace x with 2 since you need to find f(2).
[tex]\frac{11-2}{5}[/tex]
Your answer for part 2 is [tex]\frac{9}{5}[/tex].
