8x + 20
x = 20 / 8
x = 2.5
---Correction to the above statement---
This is only true if it is known that 8x+20 is equal to 0. Because the problem does not state this, we cannot assume that it is equal to 0. For example, 8x+20 could be equal to 100 making x = 10.
So, to answer your question 8x plus 20 is simply 8x+20 until it is defined what it is equal to. Then, you can solve for x.
Be sure to read the instructions carefully. For example, the problem could have asked you to factor the problem which would give you the answer 4(2x+5).
