# How to solve this statement? [closed]

How to solve this equation by removing one element? (one element is one spatially finished item.) hint :

also valid considering • Well, I suggest we Remote the equation, since the empati statement is true, I consider it solved – Viktor Jeppesen Oct 17 '18 at 7:18
• Question seems like vague or not correct. Are you asking to make a true statement by removing one element ? then change the title ... Or are you asking to make an equation by removing one element, which can be solved ? then, change the question to indicate that we should get an equation with atleast one unknown (like x) which can then be solved ... – Prem Oct 17 '18 at 15:21
• @qqjkztd , thanks ! Might be better to remove that word "equation" from the body also ! – Prem Oct 17 '18 at 15:57
• I know that when you say "one element is one spatially finished item" you think you're making things more clear, but you're not. – A. I. Breveleri Oct 17 '18 at 16:51

You'll note that there are a lot of similarities between

The shape of the 8 and the shape of the 3.

If we

Take away the parts of the 8 that are also on the 3, we're left with a 7. This is more clearly shown graphically below. A red 3 is placed over a blue 8, and the area left is a 7: So what the equation is saying is that

If we visually take a 3-shaped curve out of the 8-shape, we're left with a 7.

• That's clever! How about the hint though? I don't think it works for that. – Ahmed Abdelhameed Oct 17 '18 at 1:42
• In regards to the hint... if we XOR the 8 and the 3, the overlap cancels and you're left with a 7. – Hugh Oct 17 '18 at 2:29
• Well spotted. I think you are on the right track but the question is "How to solve this equation by removing one element?". However you didn't remove anything since you state that the equation is already solved. – xhienne Oct 17 '18 at 7:58

Here's a more serious attempt.

Subtraction: You can just about make out $$10 - 3 = 7$$. The connected-element removed is the 'v' in the top loop of the '8'. It says $$4 + 3 = 7$$. The connected-element removed is the bottom of the '8'.

The trick answer (cf 'lateral thinking' tag) is to remove the element of equality. This works for both equations.

Admittedly, it does nothing for the 'visual' tag, other than that the element of equality covers the whole spatially finished equation in each case.

:P

• This was my first thought too =) – Kroppeb Oct 17 '18 at 15:05
• I also thought about that but it doesn't become an "equation" in this case. – Ahmed Abdelhameed Oct 19 '18 at 7:19
• @AhmedAbdelhameed This was always intended as a cheeky answer. The core idea was to remove a conceptual element (not the ‘equals’ sign). If a more literal sense is required, you might consider it to be the removal of the whole equation. Problem ‘solved’. :) – Lawrence Oct 19 '18 at 11:31

Solved:

Maybe a bit too solved, there...

Don't mind my paint skills.

I copied the 7 from the right and made the pixels red to make it clear.
If you Move the 7 from the right inside the 3 on the left, it does perfectly align to be exact as the 8. Which makes the equation "8 - 8 = 0" • Gung nafjre vf qvfgenpgvat gur 3 sebz 8.(rot13) Or am I not understanding it correctly? – Thimo Demey Oct 17 '18 at 12:38

Another way to see the equation:

Remove $$-$$ sign from $$8 - 3 = 7$$, and add the slant line on $$=$$ sign: $$83 \neq 7$$

It works with $$8 + 3 = 7$$ also.

Question is very vague and I have asked OP to clarify in a comment to the question.

Meanwhile, I think to solve an "equation" we require an "unknown".
Here, the 7 is not a 7, rather it is part of a question mark "?" which is the "unknown" in the "equation" and hence 8-3=? is 8-3=5.
Similarly 8+3=? is 8+3=11. Remove the 3 and flip it L = -8
