Answer 1

16

Explanation:

Let assume that the number of video games John has is x, the number of video games Mary has then will be x + 2. Based on this, calculations are made below.

x + (x + 2) = 30

2x = 28

x = 14

Mary has (2 + 14) video games = 16

Explanation:

x+(x+2) =30

2x + 2 =30

-2 -2

2x =28

x= 14
