Question

Find the value of p and q so that the system of linear equation has infinite number of solutions 2x - y =5 and (p + q)x +( 2p-q)y =15

Answer 1

Answer:

simplifying

2x-y-5=0

9(p+q)x+(2p-q)y-15=0

2/9p+9q =1/3= -1/2p-q

p+q= 2/3  .     1 (by solving a1/a2=c1/c2)

2p-q=-3     2

by solving we get

p=-7/9
