We must collect like terms and simplify: See below

Explanation:

We must first take into consideration the variables and constants within the expression.

We have a #p#, #q# and a normal number (constant).

Now we collect like terms and simply:

#9p-5p = 4p#
#-5q+5q=0#
#9-6=3#

Now we literally we put the terms together:

#therefore# final answer #=4p+3#
