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

Do you think any ordered pairs are solutions to BOTH y=x+5 and y=-2x-1? Explain.
Rina8888 [55]

Answer:

ordered pair(-2 , 3) is the solution

Step-by-step explanation:

y=x+5

y=-2x-1

x+5 = -2x-1    substitution

x+5+2x-5 = -2x-1+2x-5

3x = -6

x = -2

y = -2+5 = 3

ordered pair(-2 , 3) is the solution
