Step-by-step explanation:
Step-by-step explanation:
I'm not sure if the question is
or
, so we can do both:
![\frac{1}{3}x + 3 = 13](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dx%20%2B%203%20%3D%2013)
First, let's subtract
from both sides to isolate the
on the left-hand side:
![\frac{1}{3}x = 10](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dx%20%3D%2010)
Next, let's multiply both sides by
to get
by itself:
![x = 30](https://tex.z-dn.net/?f=x%20%3D%2030)
![\frac{1}{3x} + 3 = 13](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3x%7D%20%2B%203%20%3D%2013)
First, let's subtract
from both sides to isolate the
on the left-hand side:
![\frac{1}{3x} = 10](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3x%7D%20%3D%2010)
Next, we can take the reciprocal of both sides to get rid of the fraction on the side with
:
![3x = \frac{1}{10}](https://tex.z-dn.net/?f=3x%20%3D%20%5Cfrac%7B1%7D%7B10%7D)
Next, we can divide both sides by
to get
by itself:
![x = \frac{1}{30}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B30%7D)
