Question

For what value of p; x = 2, y = 3 is a solution of (p+1)x-(2p+ 3)y -1=0?
(A)To Write the equation
(B) How many solutions of this equation are possible?
(C) Is this line passes through the point (-2,3)? Give justification
iwe justification​

Answer 1

(p+1)2-(2p+3)3-1=0

2p+2-6p-9-1=0

-4p-8=0

4p=-8

p=-2
