Coming from a person that can't even count, or maybe you don't know what an equation is.

Apparently you can't count either. The equation I posted was the same number of steps as yours . Now who's the smart one again ?

It doesn't matter how many steps it takes to solve it, what I posted is one equation, and your method takes more steps.

Ain't Algebra neat ! And you thought you'd never use it in real life !

OMG, thank you. I love math, and I'm not at all being facetious. Very helpful formula.
