Answer:

x = 3

y = 3/2

Step-by-step explanation:

look at the hangers to form an equation:

x + x + x + 3 + 3 + 3 = x + x + y + y + y + y

simplify

3x + 3 = 2x + 4y

x + 3 = 4y

x = 4y - 3

you also know that

x + x = y + y + y + y

2x = 4y

substitute x = 4y - 3 into this equation ^

2x = 4y

2(4y - 3) = 4y

8y - 6 = 4y

4y = 6

y = 6/4

y = 3/2

2x = 4y

2x = 12/2

2x = 6

x = 3

Divide 48 by 4 and you get 12 ounces. Therefore, each 1/4 of a bucket  is equal to 12 ounces. divide 48 by 3 and you get 16 ounces. Therefore, each 1/3 of a bucket is 16 ounces. Divide 48 by 6 and you get 8 ounces. 8 multiplyed by 5 is 40. Add 40 16 and 12 and you get 68 ounces
