See a solution process below:

First, group and combine like terms on the left side of the equation:

#-6p + 7p + 2 = 9#

#(-6 + 7)p + 2 = 9#

#1p + 2 = 9#

#p + 2 = 9#

Now, subtract #color(red)(2)# from each side of the equation to solve for #p# while keeping the equation balanced:

#p + 2 - color(red)(2) = 9 - color(red)(2)#

#p + 0 = 7#

#p = 7#
