Question

Find the value of k if (-2,3) is a solution of 2x – ky = 5.​

Answer 1

(-2,3) is the solution of 2x-ky=5

x= -2

y=3

Thus,substituting the values of x and y in the equation we get------

2(-2)-k(3)=5

-4-3k=5

-3k=5+4

-3k=9

k=9/-3

k= -3

Answer 2

Answer:

k =-3

Step-by-step explanation:

2x-ky=5

-4-3k=5

-3k=9

k=-3
