I start with 9-2x widgets. Each day, I produce 2x+1 widgets, and destroy 3-x widgets. After three days, how many widgets am I left with, in terms of x?

The net Aamount of widgets PER DAY is    2x+1      -  (3-x)   =  3x-2 w/d

 

started with  9-2x      and added three days

 

9-2x          + 3  *  (3x-2)   =     widgets after three days  ....expand and simplify
