Question

Find the value of k for which the following pair of linear equation has infinitely many solutions.2x+3y=7,(k-1)x+(k+2)y=3k

Answer 1

Answer:7

Step-by-step explanation:

Answer 2

Answer:

7

Step-by-step explanation:

Since the equations have infinite solution

2/(k-1)=3/(k+2)=7/3k

by solving this we got

=>7k-6k=7

=>k=7
