Answer:
k = 4/5
Step-by-step explanation:
5x + 2y = k , 2k + 2x + ky - 3k - 4 = 0
5x + 2y = k , 2k + 2x + ky - 3k - 4 = 05x + 2y - k = 0, -1k + 2x + ky - 4 = 0
5x + 2y = k , 2k + 2x + ky - 3k - 4 = 05x + 2y - k = 0, -1k + 2x + ky - 4 = 05x + 2y - k = 0, 2x + ky - 1k - 4 = 0
For infinity many solutions:
a1/a2 = b1/b2 = c1/c2
5/2 = 2/k = -1/-1
5k = 4
Ans: k = 4/5
