Is it possible to make this equality above true without adding, removing or moving any matchstick?

Yes, did it the same way
I too do the same...
Same Way Guillermo
Exactly Templado!
You can read it this way:
∣ + X ∣ = X
Oh man, Brilliant.Excellent Solution :D
That's what I thought as well
ingenious!
But if X is a negative number this solution is incorrect. If you take X as a Roman Number, i think |X| is not legal.

Why is it not legal?

Did Romans used Abs Values? I think it is not legal in Roman Number Math.

@Stefano Gallenda – It's not a question of whether they used it. It's just that it is a concept now and it can be used! It's all about abstract thinking.
Outstanding!
If you turn it over it is 4+1 which equals 5
Of course :) X and I are variables. The equation will be true if I = X + 1 X , for instance if X = 1 and I = 2 1 or if X = 2 and I = 3 2 .
Oh..? I just turned the picture thru 180°
Loving this app Cant believe how much i dont know .. But its good learning.
Just answer yes for this kind of question :D , lol , im sorry :(
I just saw a symmetry picture. Something with equality is balance but something balance may not equal.
Yes, it is possible by rotating the figure and see it by inverting it by 180*

Rotate the picture by 180 degrees, we have
These numbers are written in Roman numerals, X = 1 0 , I X = 9 , I = 1 . Thus equation is indeed true because X = 1 0 = 9 + 1 = I X + I .
