Question

Find the value of k for which the system kx+2y=5 and 3x+y=1 has unique solution or no solution

Answer 1

Step-by-step explanation:

if we are finding value of k for unique solution then a¹/a²=b¹/b²

i.e, k/3=2

so k=6.

however if we are finding its value for no solution

then a¹/a² should not be equal to b¹/b²

i.e, k/3 should not be equal to 2

so k should not be equal to 6

so in conclusion if unique solution k=6

if no solution k is not equal to 5
