See the entire solution process below:

Explanation:

First, multiply each side of the equation by color(red)(3) to eliminate the fraction while keeping the equation balanced:

color(red)(3) xx (p - 9)/3 = color(red)(3) xx 2

cancel(color(red)(3)) xx (p - 9)/color(red)(cancel(color(black)(3))) = 6

p - 9 = 6

Now, add color(red)(9) to each side of the equation to solve for p while keeping the equation balanced:

p - 9 + color(red)(9) = 6 + color(red)(9)

p - 0 = 15

p = 15
