Question

find the condition on system a1 x + b1 y =C1 and a a1x + b1 y = c2 to be consistent.​

Answer 1

Answer:

Correct option is

C

a2a1=b2b1=c2c1

In case of infinite many solutions ratio of the coefficients of the equations must be same.

Thus for the equations too have infinite solutions taking the ratios we get the condition

a2a1=b2b1=c2c1
