Question

The given pair of linear equations has x+2y+5=0 and -3x-6y=15 have how many solutions​

Answer 1

Answer:

Infinitely many solution because they are coincident.

Step-by-step explanation:

x+2y+5=0

-3x-6y-15=0

so, a1/a2=1/(-3)

b1/b2=2/(-6)=1/(-3)

c1/c2=5/(-15)=1/(1-3)

since,

a1/a2=b1/b2=c1/c2

hence,

they are coincident

so, infinitely many solutions will be there.
