GIVEN :
Pair of Linear equations :
i) 2x +3y=7
ii) (k+1)x+(2k-1)y=4k+1
We know that,
For infinite solutions :
a1/a2 = b1/b2 = c1/c2
From the above equations :
a1 = 2 a2 = 3 a3 = 7
b1 = k + 1 b2 = 2k - 1 b3 = 4k + 1
2/K+1 = 3/2k-1 = 7/4k+1
2/k + 1 = 3/2k - 1
4k - 2 = 3k + 3
k = 5
Therefore, the value of k is 5.
