Given equations are

2x+3y=7                                                                               ...(i)

2px+py=28−qy⇒2px+4p+qy=7                              ...(ii)

For the pair of equations have infinitely many solutions coefficient of x and y should be same.

On comparing (i) and (ii), we get

2p=2 and 4p+q=3

⇒p=4

and p+q=12⇒q=12−p=12−4=8

Hence, p=4,q=8
