A = B
Add A to both sides
A + A = A + B
2A = A + B
Subtract 2B from both sides
2A - 2B = A - B
gather terms
2(A - B) = (A - B)
Divide by (A - B)
2 = 1

A = B Add A to both sides A + A = A + B 2A = A + B Subtract 2B from both sides 2A - 2B = A - B gather terms 2(A - B) = (A - B) Divide by (A - B) 2 = 1 Just no! You cannot divide by (A-B)! |

Just no! You cannot divide by (A-B)! I know you aren't supposed to, but live a little! Actually it read like: Make a fictional, yet somewhat believable, solve to ensure A=B solves as 2=1 and break every rule of math while doing so. But, like you said, what the hell, live a little.  |
