Question

010. Find the value of panda for the following system of linear equation has infinite many solution
2x-y=5
(P+q)x+(2p-q)y=15​

Answer 1

condition for infinite no of solutions

a1/a2=b1/b2=c1/c2

according to question

2/P+Q=-1/2p-q

2(2p-q)=-p-q

4p-2q=-p-q

5p=-q+2q

5p=q

p/q=5

or p=q/5

b1/b2=c1/c2

-1/2p-q=5/15

-3=2p-q

5=p/q or

q=p/5
