Question

For which value of p does the pair of linear equations 4x +py +8 =0 and 2x +2y +2 =0 have unique solution

Answer 1

$\frac{4}{2} not \: equal \: to \frac{p}{2 } \\ so2 \: not \: equal \: to \frac{p}{2 } \\ then \: p \: notequalto \: 4$

Answer 2

Answer:

Step-by-step explanation:

4x+Py+8=0 ,2x+2y+2=0

a1/b1=a2/b2=a3/b3

4/2=p/2=2/8

4=p
