Question

Find the value of k for which the following equations are inconsistant.
x-4y=6
3x + ky = 5

Answer 1

Answer:

k= -12

is the answer for the equation to be inconsistent

pls Mark me brainliest if u like the answer

Answer 2

Answer:

x -4 y = 6

x - 4 y - 6 = 0

3x + ky - 5  = 0

as per the given condition, to make these set of equation inconsistant,

i.e, no solution  a1/b1 = a2/b2 ≠ c1 / c2

the possible value of k to make this equations     ,

    K = -12
