So let me do the algebra.
-
I claim this expression is equal to that expression,
-
so simplifying a bit I'm going to get,
-
you should just watch to make sure I don't get this wrong,
-
I'm going to get 40Q, so this implies 40Q is equal to 60(1-Q).
-
So I took this 50 onto this side and this 20 onto that side,
-
so I have 40Q is equal to 60(1-Q)
-
and that implies that Q is equal to .6.
-
So those last two steps were just algebra.
-
So what was the trick here?
-
The trick was I found Q,
