Answer:
x = 6.86
Number of video games Fletcher has = 12.58
Step-by-step explanation:
Let
Number of video games Griffin has = x
Number of video games Tommy has = 3x
Number of video games Fletcher has = 3x - 8
Total number of video games is > 40
Griffin + Tommy + Fletcher > 40
x + 3x + (3x - 8) > 40
4x + 3x - 8 > 40
7x > 40 + 8
7x > 48
x > 48 / 7
x > 6.86
Number of video games Fletcher has = 3x - 8
= 3(6.86) - 8
= 20.58 - 8
= 12.58
