Answer:
The value of k = -1 / 3x + 1 or (-1 + 3x) / 3x
Step-by-step explanation:
From equation 3x + 6y = 10, we will find y
y = 10 - 3x / 6
Putting the value of y in equation kx + 2y = 3
kx + 2 (10 - 3x / 6) = 3
kx + 10 - 3x / 3 = 3
3 kx + 10 - 3x = 9
3 kx - 3x = 9 - 10
3x (k - 1 ) = -1
k - 1 = -1 / 3x
k = -1 / 3x + 1 or (-1 + 3x) / 3x
