Question

I f (2,-5) is the solution of the equation
2x -ky= 14 then find k =?

Answer 1

Answer:

Substituting the values in equation we got

2(2) -k(-5) =14

4+5k=14

5k=14-4

5k=10

k=10/5

k=2

Answer 2

Step-by-step explanation:

2x -ky= 14

2(2) - k(-5) = 14

4 + 5k = 14

5k = 14 - 4

5k = 10

k = 2

Hope this helps you
