Question

Given that f(x) = 9x -6, what is x when f(x) = 30?

Answer 1

X = 4

Explanation:

Since both 9x-6 and 30 equal f(x), we can set them equal to each other. Like this:

9x - 6 = 30

Now, just solve the equation

Add 6 to both sides

9x = 36

Then divide 9 on both sides

x = 4

Therefore, x is equal to 4.

Check:

9(4) - 6 = 30

36 - 6 = 30

30 = 30

I hope this helps!!
