Question

5m-3n=19;m-6n=-7
please help me ​

Answer 1

Answer:

5m-3n=19. -------------. (1)

m-6n=-7. -------------- (2)

from (2),

m= -7+6n.

putting value of m in (1),

5( -7+6n) -3n=19.

-35+30n-3n=19.

27n=19+35.

27n= 54.

n=54/27.

n=2.

m= -7+6n.

m= -7+6×2.

m= -7+12.

m=5.

Answer 2

Answer:

m = 5

n = 2

Step-by-step explanation:

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

m-6n = -7

m = -7+6n   --------- (1)

5m-3n = 19

putting the value of equation (1),

5m - 3n = 19

5(-7+6n) -3n = 19

-35 + 30n -3n = 19

27n = 19+35

27n = 54

n = 54/27

n = 2

from equation (1). we get,

m = -7+6n

m = -7 + 6 × 2

m = -7 + 12

m = 5

m = 5
