2) There are 12 adult and 30 teen volunteers for a park clean-up day. Volunteers will be divided into equal-sized groups. Each group will have the
same number of adults and the same number of teens. What is the greatest
number of groups that can be formed? ||

2

Step-by-step explanation:

because 12 x 2 is 24. so if it's going to be equal it's going  to be 2

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.
