Answer:

The proportion results to


p=-146

Step-by-step explanation:

Given the proportion:


(9)/(p-7)=(8)/(p+10)

To solve for p, we multiply (p - 7)(p + 10)


(9(p-7)(p+10))/(p-7)=(8(p-7)(p+10))/(p+10)

This becomes:


9(p+10)=8(p-7)

Remove the brackets


9p+90=8p-56

Subtract 8p from both sides


\begin{gathered} 9p+90-8p=8p-56-8p \\ p+90=-56 \end{gathered}

Subtract 90 from both sides


\begin{gathered} p+90-90=-56-90 \\ p=-146 \end{gathered}
