Let's simplify
open the bracket
[tex]2p\text{ + 9-p-15}[/tex]Rearrange
2p - p + 9 - 15
p - 6
The correct options are either the same values as this directly or options that will give the same values when simplified
They are;
p- 6
[tex]3(\frac{1}{3}p+\text{ 3-5)}[/tex]when you simplify this it becomes;
p - 6
[tex]3(\frac{1}{3}p-2)[/tex]when you simplify, it gives p - 6
