Question

Find them value(s) of K so that the pair of equation x+2y=5 and 3x + KY +15=0 has unique solution.
Plz answer this ......

Answer 1

k=56 is the solution

Answer 2

Answer:

Step-by-step explanation:

A unique solution means that the lines represented by the equations intersect at one point. this happens if

3/1 # k/2, that is if k # 6.

we have a unique solution for all k different from 6.
