Question

For each of the following system of equation determine the value of k for which the given system of equation has a unique solution.
A. x - 2y = 2
B. 3x +ky = -5

Answer 1

Answer:

Step-by-step explanation:

x-2y=2

x=2+2y

Substituting the value of x in B

3x+ky=-5

3(2+2y)+ky=-5

6+6y+ky=-5

(6+k)y=-5-6

(6+k)y=-11

y=-11/6+k
