Question

find k, if equations have unique solution: x-ky-2=0 and 3x+2y+5=0​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

Given,

The system of equation are

x - ky = 2

3x + 2y = - 5

To find, the value of k = ?

Here, and

1/3is not equal to -k/2

The condition of the the system of equation has a unique solution

∴

⇒ -kis not equal to -2/3

Hence,

Answer 2

Step-by-step explanation:

Step-by-step explanation:

Given,

The system of equation are

x - ky = 2

3x + 2y = - 5

To find, the value of k = ?

Here, and

a1/a2=/=b1/b2

1/3=/= -k/2

k=/=-2/3

∴

⇒

Hence, k=/=-2/3
