1. Let the variable be x, which will be the weight of each box.
2. The equation would be total = weight of each box multiplied by the number of boxes and then that gets added to the 7 pounds
52 = 4x + 7
3. 52 = 4x + 7
Subtract 7 from both sides:
45 = 4x
Divide both sides by 4:
X = 45/4
X = 11.25
4. The weight of each care package was 11.25 pounds.
