Step-by-step explanation:
The given system of equations is
(3k+1)x+3y−2=0
(k
2
+1)x+(k−2)y−5=0
This is of the form a
1
x+b
1
y+c

=0
a

x+b
2
y+c

=0,
where, a

=3k+1,b

=3,c

=−2
and a

=k
2
+1,b

=k−2,c

=−5
For no solution, we must have

The given system of equations will have no solution, if
k
2
+1
3k+1
=
k−2
3
=
−5
−2
⇒
k

+1
3k+1
=
k−2
3
and
k−2

=
5

Now,
k

+1
3k+1
=
k−2
3
⇒(3k+1)(k−2)=3(k
2
+1)
⇒3k

−5k−2=3k

+3
⇒−5k−2=3
⇒−5k=5
⇒k=−1
Clearly,
k−2

=
5
2
for k=−1
