2 = 1 Proof

Let us use basic algebraic proofs. We begin by using X and Y as any rational value.

Let X and Y be equal values      X = Y
Multiply boths sides by X      X2 = XY
Subtract boths sides with Y2      X2 - Y2 = XY - Y2
Factor each side      (X - Y)(X + Y) = Y(X - Y)
Divide by (X - Y)      X + Y = Y
Since X = Y, substitute Y with X      X + X = X
Simplify      2X = X
Divide by X      2 = 1
