18p - 45 = 0
18p - 45 + 45 = 0 + 45
18p = 45
18p/18 = 45/18
p = 45/18
p = 2.5

18p-45=0
18p = 45
p = 45 / 15
simplify:
p = 5 / 2
It is actually very simple if you take it step by step:
18p-45=0
First add 45 to each side.
18p=45
Then divide 45 by 18.
p=45/18
Then reduce both numbers by a common a number, for
this problem, use 9.
p=5/2
5/2 is your answer to 18p-45=0.
