3(x - 5) = 8x - 30
Distribute 3 into the parenthesis:
3x - 15 = 8x - 30
Add 15 to both sides:
3x = 8x - 15
Subtract 8x to both sides:
-5x = -15
Divide -5 to both sides:
x = 3
Answer:

Step-by-step explanation:
To find the inverse of a function in equation form, first I recommend changing the f(x) to a y:
y = -6x + 6
Next step is to switch the x and y:
x = -6y + 6
Now solve for the new y:
x - 6 = -6y and

You can put the inverse notation back in for y like I did in the answer section above.
