Answer:

p = 6

Step-by-step explanation:

I'm omitting the x since you cannot have 2 unknowns.

(15 + 17 + 19 + 20 + p +23) /5 = 20      Combine the left

(94 + p) / 5 = 20                                   Multiply both sides by 5

94 + p = 20 * 5

94 + p = 100                                         Subtract 94

P = 100 - 94

P = 6
