6 + 3x = 2(2 + x)

What is this answer I need help please anytime soon

6+3x = 2(2 + x)

First we will need to open the parenthesis by multiplying the number that’s in front of them:

6+3x=4+2x

Now we need to separate the numbers from the X. By subtracting 2x from both sides:

6+3x=4+2x
-2x -2x
————————
6+x=4

Now we subtract 6 from both sides.

6+x=4
-6 -6
—————
X = -2

(0.5, -1)
   f^-1(x) and f(x) are inverse functions of each other. That means that for all x, f^-1(f(x)) = x and f(f^-1(x)) = x. So for f^-1(x) we've been given the point (-1, 0.5) which means that we have an x value of -1 and a y value of 0.5. So if we swap the x and y values, we'll have a valid point for function f(x). Therefore an x value of 0.5 and a y value of -1 will work. So the answer is (0.5, -1). Notice that no math has to be done, you just need to know the meaning of inverse functions.
