Answer 2

The weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.

Explanation:

Let the weight of the gaming machine be x and that of DVD be y. ATQ,

3x+y = 48 .....(1)

3x+5y = 72 .....(2)

Subtract equation (2) from (1)

3x+y-(3x+5y) = 48 -72

y-5y = -24

-4y = -24

y = 6

Put the value of y in equation (1).

3x+6 = 48

3x = 42

x = 14

So, the weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.
