Question

Find the value of k if the linear equations x+2y-5=0 and 3x+ky-15=0 have unique solution​

Answer 1

Step-by-step explanation:

is the question of the answer

Answer 2

Answer:

x+2y-5=0--------(1)

3x+ky-15=0------(2)

take x=5-2y

using it in equation 2.

3(5-2y) +ky -15=0

15-6y+ky-15=0

-6y+ky=0

-6y= -ky

k=6.
