Expand lhs
9p-36 = 18
Add 36 to both sides
9p = 54

Divide both sides by 9
P = 54/9

P= 6

#p=6#

Explanation:

Begin by distributing #9# to #p# and #-4#

#(9*p)+(9*-4)=18#

#9p+-36=18#

#9p-36=18#

Add #36# to both sides:

#9p-36color(red)(+36)=18color(red)(+36)#

#9p=54#

Divide #9# from both sides to isolate the variable and solve for #p#

#9/color(red)9p=54/color(red)9#

#p=6#
