Step-by-step explanation:

Answer:
The answer is C.
Step-by-step explanation:
Amelia = 5x - 13
Elliot = x = 45
total = x + 5x - 13 = 257
Elliot has 45 cans, and Amelia has 212.
3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111
15z - 21 + 18z - 22 = 32z - 28 - 111
33z - 43 = 32z - 139
33z - 32z = -139 + 43
z = - 96
