m

-
m

=>
m

2
=

m

Transposing m/3 to LHS and 1/2 to RHS, we get
=>
m
2
+
m
3
=
5

-

2
=>
3
m
+
2
m
6
=
10
-

6
Multiplying both sides by 6, we get
=>
5
m
6
×
6
=
7
6
×
6
=> 5m = 7
Dividing both sides by 5, we get
=>
5
m
5
=
7
5
=> m =
7

Verification:
Substituting m =
7
5
on both sides, we get

Hence, verified.
