Answer 1

Step-by-step explanation:

5m-30n=-35

5m-3n=19

-

___________

-27n=16

n=-16/27

Answer 2

Answer:

m=17/7,n=(85+245)×( 1 )=330× 1 =66

7 35 7 35 49

Step-by-step explanation:

5m-30n=-35

30n=5m+35

n=(5m+35)/30......(1)

5m-3n=19......(2)

putting (1)in(2),

5m-3(5m+35)/30=19

(50m-15m+105)=19×10

35m=190-105

m=85/35=17/7
