Elimination method
X+7y=10;3x-2y=7
5m-3n=19;m-6n=-7

Answer 1

10m-6n=28

m-6n= -7

=>9m=35

=>m=35/9

Answer 2

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
