Answer 1

Answer:

Step-by-step explanation:

infinite no of solutions must be equal to a1/a2=b1/b2=c1/c2

so in this ques we have

2/p+q=3/2p-q=7/21

by cross multiplication in a1/a2=b1/b2

3p+3q=4p-4q

4p-4q-3p-3q=0

p-q=0

p=q ....... (1)

in b1/b2=c1/c2

3/2p-q=1/3

9=2p-q

9=2p-p             (by 1)

9=p

as p=q

then q=9
