Question

7. x + (k + 1)y = 5
(k + 10x + 9y = 8k - 1. value of k infinitely many solution​

Answer 1

Answer:

k = 2

Step-by-step explanation:

x + ( x + 1 ) y = 5

( k + 1 ) x + 9y = 8k - 1

for infinite solutions →

( k + 1 )² = 9 , 8k - 1 = 5 ( k + 1 )

k + 1 = ± 3 , 8k - 1 = 5k + 5

k = 2, -4 , 3k = 6

k = 2

ans. k = 2

hope this helps you.
