Question

If the simultaneous equation 4x-3y=12 and (2p+q) x-(p+q)y =3b have infinitely many solution then what are the values of P and a respectively​

Answer 1

Answer:

for two lines to have many solutions ...they must be coincident lines...

so on comparing both equations

2p+q/4 = p+q/3 = 3b/12

if b=4 then 2p+q=4 and p+q=3

on solving those two equations

p=1 and q=2
