Question

Find the value of k so that the following system of equations has no solution 3x-y-5,6x-2y-k=0

Answer 1

Step-by-step explanation:

a1 =3, b1= -1, c1= -5

a2=6, b2= -2, c2= -k

For no solution,

$\frac{a1}{a2 } = \frac{b1}{b2 } \: is \: not \: equal \: to \: \frac{c1}{c2}$

So 3/6 = - 1/-2 = 1/2

-5/-k =5/k

5/k is not equal to 1/2

So k is not equal to 10.
