Question

if the pair of linear equations 13x+15y=3 and 65x+ky=6 do not, have any solution, which of the
following is true?

(a) k≠80 (c) k≠65
(b) k=75 (d) k≠75

Answer 1

Answer:

(b) k=75

Step-by-step explanation:

For no solution:-

a1/a2=b1/b2not= c1/c2

13/65=15/knot=3/6

13/65=15/k

k= 15x65

k=15x65/13

k=15x5

k=75
