Answer:
![y = 3(x +21)](https://tex.z-dn.net/?f=y%20%3D%203%28x%20%2B21%29)
Step-by-step explanation:
Find the inverse this equation:
![f(x) = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
-Take the variable
for
, because both
![y = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
-Switch both variable
and
:
![y = (\frac{1}{3}x) - 7](https://tex.z-dn.net/?f=y%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dx%29%20-%207)
![x = (\frac{1}{3}y) - 7](https://tex.z-dn.net/?f=x%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dy%29%20-%207)
-Solve for
:
![x = (\frac{1}{3}y) - 7](https://tex.z-dn.net/?f=x%20%3D%20%28%5Cfrac%7B1%7D%7B3%7Dy%29%20-%207)
-Switch sides:
![\frac{1}{3}y - 7 = x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20-%207%20%3D%20x)
-Add both side of the equation by
:
![\frac{1}{3}y - 7 + 7 = x + 7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20-%207%20%2B%207%20%20%3D%20x%20%2B%207)
![\frac{1}{3}y = x + 7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dy%20%3D%20x%20%2B%207)
-Multiply both sides by
:
![\frac{\frac{1}{3}y}{\frac{1}{3} } = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B3%7Dy%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
![y = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
-Divide
by multiplying by ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
![y = \frac{x + 7}{\frac{1}{3} }](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx%20%2B%207%7D%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
![y = 3(x +21)](https://tex.z-dn.net/?f=y%20%3D%203%28x%20%2B21%29)
Therefore, the answer is
.
