Question

8x+5y=9,kx+10y=15 has a unique solution .

Answer 1

Answer:

heya

here is ur answer

=========================

given :-

8x + 5y = 9

kx + 10y = 15

Transposing to RHS

8x+5y-9=0

kx+10y-15=0

✴ they has a unique solution ( given)

so they are intersecting lines.

a1/a2 not is equal to b1/b2 not is equal to c1/c2

a1/a2 ≠ b1/b2 ≠ c1/c2

➡ 8/k ≠ 5/10 ≠ -9/-15

➡8/k ≠ 5/10

➡8/k ≠ 1/2

➡k ≠ 8*2

➡k ≠ 16

k can have all values except 16.
