Question

on comparing the ratio of the cofficient find out whether the pair of linear equations 3x-6y=0 and 9x+10y-20=0 consistent or inconsistent ​

Answer 1

Step-by-step explanation:

here,

a1 = 3, b1 = -6

a2 = 9, b2 = 10

If the equation is to be consistent then

a1/a2 ≠ b1/b2

$\frac{a1}{a2} = \frac{3}{9} = \frac{1}{3} \\ \frac{b1}{b2} = \frac{ - 6}{10}$

Since, a1/a2 ≠ b1/b2

so the equation is consistent.
