Question

For what value of p the pair of linear equation have a unique solution (p+2)x -(2p+1)y = 3(2p-1) and 2x-3y=7

Answer 1

Answer:

the value of p is 4 , hope it works

Answer 2

Answer:

for all the values of p except 4 the pair of linear equations has unique solutions.

For p=1 x=-4 &y=-5,p=2 x=-4 &y=-5 and so on...
