Question

Find the value of ‘ k’ for which the pair 2x + 3y = 5 & 4x + Ky = 8 has no solution

Answer 1

Answer:

10000000 right now we have

Answer 2

Answer:

k=6

Step-by-step explanation:

Consider the given equations.

4x+ky+8=0    ……. (1)

2x+3y+5=0    …… (2)

The general equations,

ax+by+c=0

dx+ey+f=0

if the two lines represented by the equations ax + by + c = 0 and dx + ey + g = 0 intersect at a point. i.e., if the two lines are neither parallel nor coincident.The slopes should be equal

Or a/d=b/e

Apply the condition, now

a/d=b/e( this is condition of unique solution)

4/2=k/3

k=6

Hence, k is any real number except 6.
