Solution
23
x
+
17
y
+
11
z
=
130
Here, the maximum value of
x
=
[
130
23
]
=
5
If
x
=
5
,
17
y
+
11
z
=
15
. This will not have any positive integral solutions.
If
x
=
4
,
17
y
+
11
z
=
38
. This will not have any positive integral solutions.
If
x
=
3
,
17
y
+
11
z
=
61
⇒
y
=
1
and
z
=
4
.
If
x
=
2
,
17
y
+
11
z
=
84
⇒
y
=
3
and
z
=
3
.
If
x
=
1
,
17
y
+
11
z
=
107
⇒
y
=
5
and
z
=
2
.
