Answer:
Let
4
m
+
3
n
=
18
--- (1)
and
3
m
−
2
n
=
5
--- (2)
Multiplying the first equation by
2
, we get
8
m
+
6
n
=
36
-- (3)
Multiplying the second equation by
3
, we get
9
m
−
6
n
=
15
-- (4)
Adding equations 3, and 4 , we get
17
m
=
51
=>
m
=
3
Now, putting
m
=
3
in equation 1 we get,
12
+
3
n
=
18
=>
3
n
=
6
=>
n
=
2
