I'm confused on your question- if you want to keep everything in fraction form you can, or you can turn them into a decimal. you're adding, subtracting, multiplying or dividing fractions when you "solve" a fraction.

Hi there!

I believe your answer is:

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

Here’s why:

⸻⸻⸻⸻

To solve for 'x', we would have to use inverse operations.
We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
