Answer 1

Q.6 Here, a1=k, b1=3, c1=-(k-3)

a2=12, b2=k, c2=-k

Since, the given pair of eqns have infinitely many solutions, We can write as

a1/a2=b1/b2=c1/c2

=>  k/12=3/k=k-3/k

By solving, k/12=k-3/k we get k=6

and by solving, 3/k=k-3/k we get k=0,6

So, for k=0 or 6 the gn pair of linear eqns have infinitely many solns................
