the value of k is equal to 2
JayanthBhimavarapu:
correct!
solve the problem
for two equations in 2 variables
a1x + b1y + c = 0
a2x +b2y + c2 = 0
if they have to be co incident
the respective ratios of co efficients of x y and constant have to be equal
i hope u can solve now

3 - y + 8=0
-y=0+3-8
y=-5
6x-ky=16
6x-5×k=16
x-5k=16/6
×-k =8/3×5
x-k=24/3
x-k=8
-y=0+3-8
y=-5
6x-ky=16
6x-5×k=16
x-5k=16/6
×-k =8/3×5
x-k=24/3
x-k=8
