Answer 1

Answer:

For the first part

$\frac{a1}{a2} = \frac{1}{3} \\ \frac{b1}{b2} = \frac{ - 3}{ - 9} = \frac{1}{3} \\ \frac{c1}{c2} = \frac{ - 3}{ - 2} = \frac{3}{2} \\ it \: means \: equation \: has \: no \: sol$

for or part

$\frac{a1}{a2} = \frac{3}{6} = \frac{1}{2} \\ \frac{b1}{b2} = \frac{ - 5}{ - 10} = \frac{1}{2} \\ \frac{c1}{c2} = \frac{ 20}{ 40} = \frac{1}{2} \\ it \: means \: equation \: has \: infinitely \: many \: sol$
