Answer:
The price of one DVD is 4 and price of one CD is 5
Step-by-step explanation:
2DVDs and 2CDs = 18
3DVDs and 2CDs = 22
DVDs can be x and CDs can be y:
2x + 2y = 18
3x + 2y = 22
Subtract to get:
-x = -4
x = 4
So the price of one DVD is 4
Plug that into one of the original equations:
2x + 2y = 18
2(4) + 2y = 18
8 + 2y = 18
2y = 10
y = 5
So the price of one CD is 5
Answer:
(0,-9) You have to substitute 0 for x and solve for y
