Answer:
Ally fetched 32 pails and Robert fetched 8 pails
Step-by-step explanation:
If Robert fetched 2 pails and Ally fetched 8 pails, Ally fetched 4 times as many as Robert.
So 4R = A (where R = number of pails Robert fetched and A = number of pails Ally fetched)
If Robert fetched 24 fewer pails than Ally:
R = A - 24
Assuming you want to know how many pails ROBERT fetched:
Substitute R = A - 24 into 4R = A:
4(A - 24) = A
4A - 96 = A
3A = 96
A = 32 (so Ally fetched 32 pails)
Now substitute the found value for A into R = A - 24 to find number of pails ROBERT fetched:
R = A - 24
= 32 - 24
= 8
