Question

1) For each of the following systems of equations determine the value of k for which the given system of equations has a unique solution:

(i) X-ky = 2
3x+2y = -5

Answer 1

Answer:

k=2/-3

Step-by-step explanation:

follow me plzzzzz

Answer 2

Answer:

Rule for an unique solution is intersecting lines

a1/a2 not equal to b1 /b2

Step-by-step explanation:

x-ky-2=0

3x+2y+5=0

x=1

1/3 = k/2 = -2/5

k =?

so take any two values... let me take 1/3 and k/3 to find the value of "k"

1/3 = k/2

by cross multiplication we get :

2=3k

3k=2

k= 2/3

so k value is 2/3

1/3 = 2/3 /2 = -2/5

a1/a2 is not equal to b1/b2.

by substituting k value in the rule we get,
