Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.
![5x + 20y = 4](https://tex.z-dn.net/?f=5x%20%2B%2020y%20%3D%204)
Step 1) Add -20y to both sides.
![5x + 20y + - 20y = 4 - 20y 5x = -20y + 4](https://tex.z-dn.net/?f=5x%20%2B%2020y%20%2B%20-%2020y%20%3D%204%20-%2020y%205x%20%3D%20-20y%20%2B%204)
Step 2) Divide both sides by 5.
![\frac{5x}{5} = \frac{-20y + 4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%5Cfrac%7B-20y%20%2B%204%7D%7B5%7D%20%20)
![x = -4y + \frac{4}{5}](https://tex.z-dn.net/?f=x%20%3D%20-4y%20%2B%20%20%5Cfrac%7B4%7D%7B5%7D%20)
Final Answer:
![x = -4y + \frac{4}{5}](https://tex.z-dn.net/?f=x%20%3D%20-4y%20%2B%20%20%5Cfrac%7B4%7D%7B5%7D%20)
Now, let's solve for y.
Step 1) Add -5x to both sides.
![5x + 20y + - 5x = 4 + - 5x 20y = -5x + 4](https://tex.z-dn.net/?f=5x%20%2B%2020y%20%2B%20-%205x%20%3D%204%20%2B%20-%205x%2020y%20%3D%20-5x%20%2B%204)
Step 2) Divide both sides by 20.
![\frac{20y}{20} = \frac{-5x + 4}{20}](https://tex.z-dn.net/?f=%20%5Cfrac%7B20y%7D%7B20%7D%20%3D%20%20%5Cfrac%7B-5x%20%2B%204%7D%7B20%7D%20)
![y = \frac{-1}{4} x + \frac{1}{5}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B-1%7D%7B4%7D%20x%20%2B%20%20%5Cfrac%7B1%7D%7B5%7D%20)
Final Answer:
![y = \frac{-1}{4} x + \frac{1}{5}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B-1%7D%7B4%7D%20x%20%2B%20%20%5Cfrac%7B1%7D%7B5%7D%20)
Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)
