Question

please help..whats wrong in this?
let a=x
a+x=2x
a+x-2a=2x-2a
x-a=2(x-a)
1=2...

Answer 1

since x=a
x-a =0
one cannot divide by 0

Answer 2

@hartnn i think so

Answer 3

u mean u 'thought' so ?

Answer 4

nah!I said your answer makes sense

Answer 5

ohh...yes...any more doubts ?

Answer 6

just a minute...i have one

Answer 7

@hartnn is 0/0=infinity?

Answer 8

no,
0/0 is not defined.

Answer 9

so...
(100-100)/(100-100) is not defined
10^2-10^2/(10(10-10)) is not defined
(10+10)(10-10)/(10(10-10)) is not defined
...cancelling (10-10)
10+10/10 is not defined
20/10=2 is not defined????

Answer 10

again, cannot cancel, 10-10

Answer 11

y?

Answer 12

by cancelling 10-10=0
you are removing the part that was not defined
so the part which was defined, remains, which is 2=2
