x = y

x squared = xy
-----(multiply by x)

x squared - y squared = xy - y squared -----(subtract y2 from both sides)

(x + y)*(x - y) = y (x - y) -----(factorizing)

x + y = y -----(dividing by (x - y)

2y = y -----(substituting for x = y, the original premise)

2 = 1 -----(dividing by y)


Assert the truth with confidence!!!
