Question

if (3, -2 ) is one of the solution of 5x - ky = 8 then find k​

Answer 1

Answer:

$k = \frac{ - 7}{2}$

Step-by-step explanation:

(x, y) = (3,-2)

Put 'x = 3' and 'y = -2' in the equation.

5x - ky = 8

5(3) - k(-2) = 8

15 - (-2k) = 8

15 + 2k = 8

2k = 8 - 15

2k = -7

k = -7/2

Answer 2

Answer:

solution (k = -25)

Step-by-step explanation:

5(3) - k(-2) = 8

15 - k(-2) = 8

15 - (-2) = 8 + K

-17 -8 = K

-25= K
