Joe bought some CD's and DVD's at the store.

Answer 1

Answer: x=8 and y=4

Step-by-step explanation:

x+y=12           x=12-y                     x=12-4

14x+22y=200                                x=8

14(12-y)+22y=200

168-14y+22y=200

-168                 -168

-14y+22y=32

8y=32

8y/8=32/8

y=4
