Answer:
3p + q =7
2p - 2q = -6
6p +2q = 14
2p -2q = -6
8p = 8
p = 1
so q = 4
Step-by-step explanation:
Answer:
P= 1, q= 4
Step-by-step explanation:
3p + q = 7 -------------(1)
q=7-3p ------------------(1a)
2p- 2q= -6 -------------(2)
Substitute (1a) in (2)
We have :
2p - 2( 7- 3p) = -6
2p -14 + 6p = -6
8p= 14-6= 8
P= 8/8 =1
From, q=7 -3(1)
q= 7-3
q= 4
