Answer: x=1/9
Step-by-step explanation:
![2\left(\frac{1}{9}\right)x=\frac{2}{81}](https://tex.z-dn.net/?f=2%5Cleft%28%5Cfrac%7B1%7D%7B9%7D%5Cright%29x%3D%5Cfrac%7B2%7D%7B81%7D)
![\frac{2}{9}x=\frac{2}{81}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B9%7Dx%3D%5Cfrac%7B2%7D%7B81%7D)
multiply both sides by 9
![9\cdot \frac{2}{9}x=\frac{2\cdot \:9}{81}](https://tex.z-dn.net/?f=9%5Ccdot%20%5Cfrac%7B2%7D%7B9%7Dx%3D%5Cfrac%7B2%5Ccdot%20%5C%3A9%7D%7B81%7D)
![2x=\frac{2}{9}](https://tex.z-dn.net/?f=2x%3D%5Cfrac%7B2%7D%7B9%7D)
divide 2 on both sides
![x=\frac{1}{9}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B9%7D)

Answer:
95 - 9x
Step-by-step explanation:
All caves have ; 2 or 3 portals
Total portals = 95 more than number of caves
Let :
Number of 3 portal caves = x
Number of 2 portal caves = 3x
Total Number of portals :
3x + 2(3x) = 3x + 6x = 9x
Number of caves :
95 - 9x
