Question

On comparing the ratios of the coefficients, find out whether the pair of

equations x – 2y =0 and 3x + 4y -20 =0 is consistent or inconsistent.​

Answer 1

Step-by-step explanation:

a1=1 b1=-2 c1= 0

a2=3 b2=4 c2=-20

a1/a2=1/3 ,,b1/b2=2/4=1/2 ,;; c1/c2= 0/-20

1/3 not=1/2not=0/-20

so the equations are inconsistent

Answer 2

Answer:

Step-by-step explanation:

a1=1 b1=-2 c1= 0

a2=3 b2=4 c2=-20

a1/a2=1/3 ,,b1/b2=2/4=1/2 ,;; c1/c2= 0/-20

1/3 not=1/2not=0/-20

so the equations are inconsistent
