Question

A
13. For what value of p, the following equations have infinitely many solutions.
px -- 5y-20 = 0
6x - 10y - 40 = 0​

Answer 1

Answer:

P=3

Explanation:

take p=3 then,

a1/a2 = 3/6 = 1/2

b1/b2 = 5/10 = 1/2

c1/c2 = 20/40 = 1/2

therefore a1/a2=b1/b2=c1/c2

hence the equations have many solutions
