You have to replace the p and the q in the expressiogn with each given value like this:
7-5(1)+3(7) = 7-5+21 = 23

Answer:

23

Step-by-step explanation: You have to substitute 1 for p & 7 for q. Use GEMDAS/PEMDAS :D

7 - 5p+ 3q

7 - 5(1) + 3(7)

7 - 5 + 21

7 + 16

= 23


Hope this helps you!!! :)
