A basic logic puzzle with character!

Question

120 + 170 + 78 = x

Question

Is the above equation correct? Please answer Yes or No with reasons (at least three good and very specific reasons which can be seen clearly once you understand).*

---

Notes

1. Well actually they can be seen clearly even if you don't understand! Hints will follow at some point if necessary.

2. The three reasons all apply to the same answer. There aren't three reasons and three different answers.

3. The necessary clues are there. If you don't get the 3 clues you won't get the complete answer.

Answer 1

The answer is

Yes, because according to wikipedia,

the UTF-8 decimal value for the Latin Small Letter x is 120.
While the hex value for the Latin Small Letter x is 78.

Additionally, the octal value of the Lowercase x is 170.
(Thanks to @Stiv for pointing me to the necessary list)

Using “+” as a logical symbol for “or”, we get 120 or 170 or 78 = x.

So, the answer would be yes.

However, finding the three clues that links the three to this answer was quite trying.

My first thought is the usage of x to mean cross or trans. So, by transposing the three exes atop one another, creates one x. (Which turns out was not the OP’s intention)

My second thought is the title using the words as the clues was confirmed by OP.

- "character" clues to the use of a character code chart to find x's value.

- "basic" clues to the use of BASE-n coding, dec(Base-10) ,hex(Base-16), oct(Base-8)

- "logic" as pointed out by OP refers to basic logic symbols where “+” is substituted for the word “or”. So the equation means a or b or c = x.

Answer 2

One of the answers are:

YES
x is a variable which means it is mutable allowing you to make it any number you want
