Question

The pair of linear equations 2x+ky=k,4x+2y=k+1 has infinitely many solutions if
pls solve the equation ​

Answer 1

Answer:

k=1

Step-by-step explanation:

2x+ky—k=0

4x+2y−(k+1)=0

here ,a1=2 ,b1=k ,c3=-k

and a2=4, b2=2,c3= -k+1

For the system to have infinite solution,

a1/a2=b1/b2=c1/c2

=>2/4=k/2=(-k)/-(k+1)

=> 4k=4

=>k=1
