Let small box = X and large box = y
Set up two equations:
X + Y = 85 pounds.
Rewrite as X = 85 - y
and:
55x + 50Y = 4375 pounds.
Replace x:
55(85 - y) + 50y = 4375
Use distributive property:
4675 - 55y + 50y = 4375
Combine like terms:
4675 - 5y = 4375
Subtract 4675 from both sides:
-5y = -300
Divide both sides by -5:
y = 60
This is the weight of the large box.
The small box would weigh 85 - 60 = 25 pounds.
Large box = 60 pounds.
Small box = 25 pounds.
