]]>1=1 [To start]

a=b [Got it?]

a•a=b•a [Both sides multiplied by a]

a^2=ab [Which is]

a^2-b^2=ab-b^2 [Subtraction axiom with b^2]

(a+b)(a-b)=b(a-b) [Factored]

(a+b)(a-b)/(a-b)=b(a-b)/(a-b) [Divide both sides by (a-b)]

a+b=b [Which is]

b+b=b [Unnecessary step but shows the result easier]

2b=b [Which is]

2=1 [Equals]
