Harry went to collect eggs from four chicken coops. At the first coop he collected the eggs and put them in the basket.at the next coop,he doubled what he had.At the third coop, he collected 6 more but dropped and broke two on his way to the fourth coop. At the fourth coop, he added 4 more eggs. On his way home, he gave half of the eggs to his grandma and took the remaining nine eggs home to his mother. Explain how you solved this problem. How many eggs did Harry collect at the first coop?

X = the number of eggs collected at the first coop.
Then, after Coop 1 = X
......after coop 2 = 2X
......after coop 3 2X + 4
......after coop 4 2X + 8
Gave half to grandma leaving X + 4
Gave the remaining 9 to his mother
Making X + 4 = 9 or X = 5.
