Question

5) If (2,-5) is the solution of the equation 2x - k y = 14 then find k
=?​

Answer 1

put x = 2 and y= -5

then u will get

4+5k= 14

5k = 10

k= 2

Answer 2

Answer:

k = 2

Step-by-step explanation:

(x, y) = (2, -5)

2x - ky = 14

Simply substitute the values of x and y into the equation:

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

4 + 5k = 14

5k = 14 - 4

5k = 10

k = 10/5

k = 2
