Question

if the system of equations 6x+2y=3 and kx+y=2 has unique solution find k​

Answer 1

Answer:k is not equal to 3

Step-by-step explanation: for the value of k to be unique...

a1/A2 is not equal to b1/b2

6/k is not equal to 2/1 and hence on solving the answer is value of k is not equal to 3

Answer 2

Answer:

a1=6 ,b1=2,c1=-3

a2=k,b2=1,c2=-2

unique solution

a1/a2does not equalb1/b2

6/k=2/1

6=2k(here using by cross multiplying)

6/3=k

2=k
