Answer 2

Answer:

m = 40

n = 10

Solution:

Here,

The given equations are :

-m + 5n = 10 --------(1)

2m - 5n = 30 --------(2)

Now,

Adding eq-(1) and (2) , we get ;

=> - m + 5n + 2m - 5n = 10 + 30

=> 2m - m = 40

=> m = 40

Now ,

Putting m = 40 in eq-(1) , we get ;

=> - m + 5n = 10

=> - 40 + 5n = 10

=> 5n = 10 + 40

=> 5n = 50

=> n = 50/5

=> n = 10

Hence,

m = 40

n = 10
