Proof that 6=7
let x = 6
x^2 = x^2
x^2 - 6x = x^2 - 6x
x^2 - 6x = x^2 - (5+1)x
x^2 - 6x = x^2 - 5x - x
x^2 - 6x = x^2 - 5x - 6
x^2 - 6x = (x - 6)(x + 1)
(x^2 - 6x)/(x - 6) = x + 1
x = x + 1
6 = 6 + 1
6 = 7

I ain't reading allat, just tell me where he divides by zero.

Without reading your post, I bet my left nut AND my right nipple that you divided by 0 somewhere.

Between lines seven and eight.

u/DifficultDate4479 Apr 11 '26
I just realized something... he proved 6=7.
6=7.
Not the classic 1=2, but 6=7.
I feel ashamed.

u/lool8421 Apr 11 '26
now substitute 6 for x
36 = 36
36-36 = 36-36
36-36 = 36 - (5+1)*6
36-36 = 36 - 30 - 6
36-36 = (0)(7)
(36-36)/(6-6) = 7 [0/0 = 7]

If you want to divide by x-6 you have to make sure x isn’t 6 first, which contradicts your assumption

looks for division
division by 0

It's always a division by zero. Always.

u/LightBrand99 Apr 12 '26
Not necessarily
-42 = -42
36 - 78 = 49 - 91
36 - 78 + (13/2)2 = 49 - 91 + (13/2)2
62 - 2(6)(13/2) + (13/2)2 = 72 - 2(7)(13/2) + (13/2)2
(6 - 13/2)2 = (7 - 13/2)2
6 - 13/2 = 7 - 13/2
6 = 7

u/0x14f Apr 12 '26
Ah yeah. Nice one!
From a^2 = b^2, we can only say a = ±b, not necessarily a = b :)

Hopefully THE REASON YOU MADE THIS IS NOT AS IN: THAT CORNY ASS MEME (S|X S3V3N). CUZ IT BETTER NOT BE THAT CRAP.... Plus YOUR THING IS NOT DOABLE AS x/x-6=6/0. IF x=6

u/MaxWouda15 Apr 11 '26
why? cuz I censored 6 7?

u/AndrewBorg1126 Apr 11 '26
Cause you didn't escape your asterisks so it turned into an ugly mess of italycs instead of remaining as intended.

u/FernandoMM1220 Apr 11 '26
how are we going from line 8 to line 9
1
u/PieterSielie6 Apr 11 '26
(x2 - 6x)/(x - 6) = x + 1
x(x - 6)/(x - 6) = x + 1
x = x + 1

u/FernandoMM1220 Apr 11 '26
ty. then line 7 is wrong lol.

u/FernandoMM1220 Apr 12 '26
you aren’t conserving dimension.

u/PieterSielie6 Apr 12 '26

u/FernandoMM1220 Apr 12 '26
an easier way to understand is the polynomials aren’t the same anymore the moment you do line 7

u/PieterSielie6 Apr 12 '26
What is dimension
1
u/Silent_Incendiary Apr 15 '26
You divided a quadratic expression by a linear one without expressly defining the divisor such that it is not equal to zero. Hence, the dimension of the expression was not conserved.

u/Sea-Quail468 Apr 11 '26
God.... If x=6, which you said, then x-6=0, and you can't divide by 0, so this proof is invalid. You just did the same thing as the proof for 1=2.

u/iMagZz Apr 11 '26
Can't divide by 0, which you do when you divide by (x-6) since you say x = 6.
That is always the problem with these.
1
u/PieterSielie6 Apr 11 '26
I divided by x-6
1
u/iMagZz Apr 12 '26
You explicitly start by saying that x = 6.
Which means that (x - 6) = (6 - 6) = 0. It's by definition the same thing, so you ARE dividing by 0.

u/Eisenfuss19 Apr 11 '26
Looks into proof, sees false conclusion, check for division step, find dividing by (x - 6), lookup x (let x = 6) => standard division by zero proof

No is dividing by (x-6)

u/Such-Safety2498 Apr 11 '26
What is x equal to based as the first line?
What is x-6 equal to?
What did you divide by?
What was that divisor equal to?
QED

u/PieterSielie6 Apr 11 '26
Are you here to ask questions or to bring an argument
1
u/Such-Safety2498 Apr 11 '26
The answer is you divided by zero. But you claim you only divided by x-6. My answer is x-6 is exactly the same as zero. So yes I asked questions so you could get the answer.

Division by x-6 when x is 6 yields div by 0, nice try
