Answer:
[tex]p = - \frac{25}{2} = - 12 \frac{1}{2} = - 12.5[/tex]
Step-by-step explanation:
[tex]5(2p - 4(p + 5)) = 25[/tex]
[tex]2p - 4(p + 5) = 5[/tex]
[tex]2p - 4p - 20 = 5[/tex]
[tex] - 2p - 20 = 5[/tex]
[tex] - 2p = 5 + 20[/tex]
[tex] - 2p = 25[/tex]
[tex]\boxed{\green{p = - \frac{25}{2} = - 12 \frac{1}{2} = - 12.5}}[/tex]
