Irena is putting together 6 goodie bags with chocolate and hard candy for her birthday party. she puts 4 pieces of hard candy in each goodie bag. once she is done, she has placed a total of 42 items in bags.
how many pieces of chocolate did she put in each goodie bag?

3 pieces of chocolate

Step-by-step explanation:

42 divided by 6 = 7 items per bag

7- 4 = 3

To check:

4 + 3 = 7 * 6 = 42

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
