Can anyone help me with this question? It would really help a lot!

Answer:
32 games in Preston's collection
Step-by-step explanation:
Preston's collection - x
Justis's collection - 3x (3 times the collection of Preson's)
Total number - 128
x + 3x = 128
4x = 128
[tex]\frac{4x}{4} = \frac{128}{4}[/tex]
x = 32
