Question

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

Answer 1

multiply second equation by 5 and then subtract 1 and 2 equation
then u get
-3n+30n=19+35
27n=54
n=2
from 2 equation u get
m-6(2)=-7
m-12=-7
m=5
hope it helps!!

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
