Question

For what value of p, 2x +2y =-2 and 4x+py =-8 will have unique solution​

Answer 1

Answer:

p=3

Step-by-step explanation:

a1=2,a2=4,b1=2,b2=p ,c1=2. ,c2=8

we know that if a1/a2not equal to b1/b2 then it has unique solution

2/4=2/p

if p=3then 2/4 is not equal to 2/p

2/4 not equal to 2/3 and it is a unique solution

p=3 is the correct answer
