Solution :-
5m - 3m = 19 ..................(1)
m - 6n = - 7 .....................(2)
5m - 3m = 19
⇒ 2m = 19
⇒ m = 19/2
⇒ m = 9.5
Substituting the value of m = 9.5 in (2)
⇒ m - 6n = - 7
⇒ 9.5 - 6n = - 7
⇒ - 6n = - 7 - 9.5
⇒ - 6n = - 16.5
⇒ 6n = 16.5
⇒ n = 16.5/6
⇒ n = 2.75
So, the value of m is 9.5 and the value of n is 2.75.
