Answer:
x = 27
Step-by-step explanation:
I'm assuming the equation looks like this:
![\frac{2}{3}x-\frac{1}{9}x+5=20](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx-%5Cfrac%7B1%7D%7B9%7Dx%2B5%3D20)
Here's how to solve for x:
![\frac{2}{3}x-\frac{1}{9}x+5=20](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx-%5Cfrac%7B1%7D%7B9%7Dx%2B5%3D20)
(subtract 5 from both sides)
![\frac{2}{3}x-\frac{1}{9}x=15](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx-%5Cfrac%7B1%7D%7B9%7Dx%3D15)
(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)
![\frac{6}{9}x-\frac{1}{9}x=15](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B9%7Dx-%5Cfrac%7B1%7D%7B9%7Dx%3D15)
(add like terms)
![\frac{5}{9}x=15](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7Dx%3D15)
(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)
x = 27
