Answer:

5m - 3n = 19

m - 6n = -7

=> 10m - 6n = 38

m - 6n = -7

=> on subtracting

9m = 27

m = 27/9 = 3

Answered by OoINTROVERToO

Step-by-step explanation:

5m - 3n = 19 m - 6n = -7

10m - 6n = 38 m - 6n = -7

SUBTRACT

10m - 6n - (m - 6n) = 38 - (-7)

10m - 6n - m + 6n = 38 + 7

9m = 45

m = 5

5 - 6n = -7

6n = 12

n = 2
