Question

ax + by = c and mx + ny = d and an + bm then these simultaneous
equations have -
(A) Only one common solution.
(B) No solution.
(C) Infinite number of solutions.
(D) Only two solutions,

EXPLAIN WITH PROOF !!!!​

Answer 1

HeyFriend:)

We have been given two equations :-

ax + by = c

and mx + ny = d

also,

an ≠ bm

=> a/m ≠ b/n

which is a condition for unique solution

so, the answer is

A) only one solution
