Question

solve this equation​

Answer 1

Answer:

k ka mann hoga -3. so right answer is B.

Answer 2

Answer: Here's ur answer....

kx-y=2 and 6x-2y=3

so, let, a1=k , b1=-1 , c1=2

and , a2=6 , b2=-2 , c2=3

so, for infinitely many solutions,

a1/a2=b1/b2=c1/c2

=) k/6 = -1/-2 = 2/3

now, k/6 = -1/-2 also, k/6=2/3

=) k/6 = 1/2 =) 3k=12

=) 2k=6 =) k=12/3=4

=) k=6/2=3 =) k=4

=) k=3

so, the value of k is either 3 or 4

but as it is given 3 in option

so, value of k is 3 (A)
