Question

obtain the condition of the following system of a linear equation to have a unique solution: ax+by+c=0 ; lx+my+n=0 guys plz help me with this problem... will surely mark the answer as brainliest

Answer 1

Answer:

Solution. a1x+b1y+c1=0. a2x+b2y+c2=0. Where a1=1,b1=2,c1=−c. And a2=l,b2=m,c2=−n.

Answer 2

Answer:

The condition of the following system of a linear equation to have a unique solution is

[ Coefficient of x in 1st equation / Coefficient of x in 2nd equation] # [ Coefficient of y in 1st equation / Coefficient of y in 2nd equation]

So

( a / l ) # ( b/ m)

Which is the required condition
