Solve the following system of equations:
2x + 3y = 40
-2x + 2y = 20
We can add these equations to get a new equation. Then we can solve for y:
0 + 5y = 60
5y = 60
y = 12
2x + 3y = 40, plug in y = 12 and solve for x:
2x + 36 = 40
2x = 4
x = 2
Choice A

Answer: 33.35 Pounds for each box.
Step-by-step explanation: Well first you take the weight of the empty box, 0.98, and then the weight of the packaging material, 1.74. You add that and get 2.72. So then you take the weight of the packages and minus the wight of the packaging material. 69.42-2.72=66.7. SO then you divide that by two and your answer 33.35. I am pretty sure this is the right answer, if not then I am sorry. Hope this helps.
