Problema Solution
A clown is preparing for a party by inflating one balloon for every
invited guest. Just when she has half of the
necessary balloons inflated, 3 of them pop. She inflates 5 more
balloons, and two pop. Then 6 balloons are carried away by the wind.
She finishes by inflating 16 more balloons, and then learns that only
12 guest will attend the party. How many extra balloons did the clown
inflate? HOW DO YOU SET UP THIS PROBLEM AND SOLVE IT??

Ok so you have x amount of guests to begin with.
So x equals half of x minus three, then you add five and subtract two, so far leaving you with x=.5x, then you subtract six and then add 16. x=.5x+10, so then you subtract .5x which equals .5x=10, then divide by .5, giving you 20=x. Since only twelve people are attending, you would subtract 12 from 20, and you get 8.
