Question

for what values of k will the following pair of linear equation have no solution ?
8x +5y=9 ; kx+ 10y =12

Answer 1

Answer:

k=16

Step-by-step explanation:

if the pair has no soln then

a1/a2=b1/b2 not = c1/c2

8/k=5/10 not=9/12

taking 8/k=5/10 (for finding k)

8/k=1/2

k=8×2

k=16

you may put the value of k in above condition it will satisfy it
