Question

For which values of p, does the pair of equations given below has unique solution? 4x + py + 8 = 0 and 2x + 2y + 2 = 0




​

Answer 1

Answer:

P is not equal to 4.

Step-by-step explanation:

4x+py+8=0

a1=4,b1=p

2x+2y+2=0

a2=2,b2=2

for the equations to be unique

a1\a2 should not be equal to b1\b2

==4\2 should not be equal to p\2
