Question

Find the value of k for which the pair of equations 2x+ (k+1 ) y= 3k + 1 and 4x + 6y=21 has a unique solution​?

Answer 1

Step-by-step explanation:

unique solution means it is a intersection of two lines.

a1/a2 not equals to b1/b2

2/4=1/2

k+1/6

when k is equal to 2 it becomes parallel lines so except k=2 all values of k will work to find unique solution.
