Answer:
p = 3
q = 5
Step-by-step explanation:
5 p + q = 20 ------------------------------ 1
4 p + 5 q = 37-----------------------------2
from eq 1
q = 20 - 5 p -------------------------------3
put this value in eq 2
4 p + 5 ( 20 - 5 p ) = 37
4 p + 100 - 25 p =37
- 21 p = - 63
p = 3
put this value in eq 3
q = 20 - 5 p
q = 20 - 15
q = 5
