Question

prove that 1 = 2. You can use variables and basic maths will help.

Answer 1

Solution: Given below.

Answer 2

Did that in my college ;)

Let, x=1 y=1 ----- eqn 1.
hence, x=y

multiply with y on both sides, 
xy = y^2

substract x^2 on both sides.
xy - x^2 = y^2 - x^2
xy - x^2 = (y-x) (y+x) [using formula of x^2-y^2]

deduce common elements
x(y-x) = (y-x) (y+x) 

cancel (y-x) on both sides. 

x = (y+x) 

Substitute values from eqn 1

1 = (1+1)
1=2
Hence Proved.
