9x-22=23+4x I don't understand how to do this

1 answer:

4 0

9x-22=23+4x Now you subtract 4x from both sides to get the variable on one side.. 5x-22=23 Now solve as you would solve a 2 step equation. 5x=45 Divide both sides by 5 to get the variable by itself. x=9

Answer:

To find f-¹(x) of f(x) equate f(x) to y

That's

f(x) = y

So we have

$y = \frac{4x - 7}{10}$

Next interchange the variables that's x becomes y and y becomes x

That's

$x = \frac{4y - 7}{10}$

Next make y the subject

Cross multiply

We have

4y - 7 = 10x

Move -7 to the right side of the equation

4y = 10x + 7

Divide both sides by 4

We have the final answer as

$y = \frac{10x + 7}{4}$

$f ^{ - 1} (x) = \frac{10x + 7}{4}$
