Question

If am bl then the system of equations ax + by = c, lx + my = n, has (a) a unique solution (b) no solution (c) infinitely many solutions (d) none of these

Answer 1

Answer:

c is right answer

please mark to brain list and do follow me

Answer 2

Answer:

Answer:

ax+ by = c

lx + my = n

a1 = a. , a2= l

b1 = b. , b2= m

c1 = c. ,c2= n

it is given that,

am ≠ bl

therefore, a/l ≠ b/m

so, it has a unique solution

so, option a is a correct answer
