Let
	Let a	=	b
Multiply both sides by a
	a²	=	ab
Add a² to both sides
	a² + a²	=	a² + ab
Collect like terms on both sides
	2a²	=	a² + ab
Subtract 2ab from both sides
	2a² - 2ab	=	a² + ab - 2ab
Factor the left side, and collect like terms on the right side.
	2(a² - ab)	=	a² - ab
Divide both sides by (a² - ab)
	2	=	1
