Simple math - regdude - 31.10.2010
Hi!
I forgot how to solve an equation, lol!
So there are some numbers and Xs and at the end I get:
-10x=-10x+6
-10x+10x=6
0x=6
How was it... x is equal to any number or x is equal to non-existing number (undef.)?
It seems that if I take any number then I get 0 and that means 0=6, kinda wrong, so it would be undef. as the answer.
Re: Simple math - CJ101 - 31.10.2010
if i remeber my math class right, x = 1.
i might have failed though.
Re: Simple math - Mauzen - 01.11.2010
This equation cant be solved, because in the last line it says
0=6. So x is not defined.
Re: Simple math - iFriSki - 01.11.2010
There would be no solution for this.
Re: Simple math - cessil - 01.11.2010
Possibly completely wrong here because I haven't done this since before 2007
-10x=-10x+6
-10x+10x = 6
(-10x+10x)/-10 = 6/-10
x+-1x = 6/-10
x-1x = 6/-10
(x-1x)+1 = -0.6 + 1
2x = 0.4
2x/2 = 0.4/2
x = 0.2
EDIT: well if the top one is the original equation then there would be no proper answer since no number could be the same as itself +6.
EDIT2:
quicker more accurate way.
-10x=-10x+6
-10x/-10 = -10x/-10 + 6
x = x + 6

As simple as 10x is not equal to 10x + 6.
Re: Simple math - ViruZZzZ_ChiLLL - 01.11.2010
EDIT :
Код:
-10x = -10x + 6 -10x + 10x = 6 It's null set or Impossible to solve. X cannot be 0.
Re: Simple math - Zimon95 - 01.11.2010
0x = 6
It's impossible because there is no value of X that would result 6 if multiplied by 0.
Re: Simple math - DiDok - 01.11.2010
There IS a solution for this...
If you do the equation the result is 0=6, it's called:
EMPTY SET (or null set, don't know exact English term)
This is the proper answer
Re: Simple math - Westie - 01.11.2010
Yes, it is indeed an empty set.
It may just be possible that you have re-arranged wrong somewhere before that point.
