Prove that 2=1

The Sillyyyy Solution ....

Let x,y be two variables and let x = y

multiplying both sides by x we get

x^2 = xy

now, subtracting both sides by y^2 we get

x^2 - y^2 = xy - y^2

=> (x + y)(x - y) = y(x - y)

=> (x + y) = y

now since x = y (assumed above) we get

=> (x + x) = x

=> 2x = x

=> 2 = 1


Hence proved ..........
