Question

are 2x + 3y + 5 =0 and 4x + 6x + 7 =0 consistent?

Answer 1

Here A1=2 ,b1=3 c1=5

And A2=4,b2=6,c2=7


compare them


2/4=1/2

3/6=1/2

5/7=5/7

So from above 1/2=1/2is not equal to 5/7


So,it is inconsistent.

Answer 2

a1=2,b1=3,c1=5
a2=4 ,b2=6 ,c2=7
$\frac{a1}{a2} = \frac{2}{4} = \frac{1}{2} \\ \frac{b1}{b2} = \frac{3}{6} = \frac{1}{2} \\ \frac{c1}{c2} = \frac{5}{7} \\ \frac{a1}{a2} = \frac{b1}{b2} =/ \frac{c1}{c2} \\ hence \: the \: equations \: are \: inconsistent$
