Question

ax+by=c and mx+ny= d and an not equal to bm then these simultaneous equations have *

Answer 1

Hi ,

********************************************

Relation between the coefficients and 

nature of system of equations.

ax+ by - c = 0 , mx + ny - d = 0 are two

linear equations ,

if a/m ≠ b/n

or 
an ≠ bm

then the pair of linear

equations is consistent.

The lines intersecting each other .

Therefore ,

they have one common point 

and one Unique solution.
******************************************†

Option ( A ) is correct.

I hope this helps you.
