Question

2X+3Y=7 AND 2PX+PY=28-QY FIND P AND Q

Answer 1

Step-by-step explanation:

Answer

Given equations are

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

2px+py=28−qy⇒

2

p

x+

4

p+q

y=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

2

p

=2 and

4

p+q

=3

⇒p=4

and p+q=12⇒q=12−p=12−4=8

Hence, p=4,q=8
