5p + 2 = 13.25 (we'll have to separate the numbers with the variables and the naked numbers)
5p = 13.25 - 2 (when you switch their places their symbol changes - goes to + then + goes to -) - is negative and + is positive, as in adding and subtracting.
5p = 11.25
p = 11.25/5 (since theirs multiplication in 5p (5 x p) we're going to do division)
