Question

16)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
B) k=75
C)k#65
D) k#75
17​

Answer 1

Answer:

k=75

Step-by-step explanation:

In linear equation ,when no solution then equation must satisfy the condition

a1/a2=b1/b2 (=\)not equals to c1/c2

i.e

In above question

a1= 13

b1=15

c1=3

a2=65

b2=k

c2=6

then

A/C

1/5 = 15/k

k= 75
