But from what I understood.
(1/2) * (3) = (3/2)
And
(1/2) + (3) = (1/2) + (6/2) = (7/2)
So how can the (3) just combine with the (1/3t) when there is a + sign separating them?????
Then ???
*Can anyone please at least tell me if I understood it wrong. I've been reading my book and doing the problems and it all seems to follow that rule. I don't understand why this problem is different.*
