You were busy working on a problem using 4 big squares, 8 rectangles, and 8 small squares. Your partner accidentally knocked some algebra tiles off the your desk. You now have 1 big square, 3 rectangles, and 5 small squares on your desk.
Write and algebraic equation that shows what tiles you began with, what you partner knocked off the desk, and how many tiles you have left.
errrr, I don't get it?
begin --> 4b+8r+8s
end ----> (4-x)b+(8-y)r +(8-z)s =1b+3r+5s
(4-x)=1 so x = 3
(8-y)=3 so y = 5
(8-z)=5 so z = 3
