Question

.How many solutions to the pair of equations
x+2y + 5=0 and -3x-6y+1=0 write without doing actual
proces​

Answer 1

Answer:

NO SOLUTIONS

Step-by-step explanation:

Answer 2

Answer:

x + 2y + 5 = 0 ...........(i)

-3x - 6y + 1 = 0

3x + 6y -1 = 0 ...........(ii)

than the a1 = 1, b1 = 2, c1 = 5

a2 = 3, b2 = 6, c2 = -1

$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2} \\ \frac{1}{3} = \frac{2}{6} = \frac{5}{ - 1} \\ \frac{1}{3} = \frac{1}{3} = \frac{5}{ - 1} \\ \frac{a1}{a2} = \frac{b1}{b2} is \: not = \frac{c1}{c2}$

Hence the is question is Parallel line so this is no solution.
