HEY THERE!!

Given function:- 3x-3y=18

=> 3(x-y)= 18

Now divide by 3 on both sides.
=> x-y = 6

Now subtract with x on both sides
=> -y = 6-x

Divide by - from both sides.
=> y = x-6
or f(x)= x-6

HOPE IT HELPED YOU.

First you would have to isolate y.
3x - 3y = 18 -----> Subtract 3x from both sides
-3y = -3x + 18 --------> Now divide both sides by -3
y= x - 6

Now you replace the y with an f(x)
f(x) = x - 6
