Question

Por favor alguien que me ayude:
2×(3+m)+(-5)×(m+1)=0

Answer 1

2x(3+m)+(-5)x(m+1)= 0
6 + 2m + (-5m - 5) = 0
6 + 2m - 5m - 5 = 0
1 - 3m = 0
m = -1/3


....................Kd

Answer 2

Resolvemos :

2(3 + m) + (- 5)(m + 1) = 0

6 + 2m - 5m - 5 = 0

2m - 5m =  5 - 6

- 3m = - 1

    m = - 1/ - 3

    m = 1/3
