Question

assertion: the value of k if 3x -4y =7 , 6x -8y =k have infinite number of solution is 14. reason: if the given equation has infinite number of solution then a1/a2 is not equal to c1/c2​

Answer 1

in two equation when a1/a2=b1/b2=c1/c2

then the equation have infinity solution

here a1/a2=3/6=1/2

b1/b2=-4/-8=1/2

c1/c2=-7/k

-7/-14 (k=-14. given)

=1/2

hense 1/2=1/2=2/2
