Question

Find values for p and q so that the equation has infinitely many solutions.
px–2=4x+x+q

Answer 1

Answer:

I have given the answer was it helpful

Step-by-step explanation:

This system of equation is of the form

a1x+b1y=c1

a2x+b2y=c2

where a1=2,b1=3,c1=7 

and a2=p+q,b2=2p−q and c2=21

For infinitely many solutions, we must have

a2a1=b2b1=c2c1

The given system of equations will have infinite number of solutions, if

p+q2=2p−q3=217

⇒p+q2=2p−q3
