Question

como resolver 3m-5/2=m-3/5

Answer 1

3m - 5/2 = m - 3/5
3m - m = -3/5 + 5/2
2m = -6/10 + 25/10
2m = 19/10
m = 19/10 . 1/2
m = 19/20

Answer 2

Olá, boa noite! ☺

Bem, vamos lá ...

Prezado amigo (a), com base no enunciado que temos acima, podemos entender que:

$\displaystyle \mathsf {3m - \dfrac {5}{2} = m - \dfrac {3}{5}}$

$\displaystyle \mathsf {3m - m = -\dfrac {3}{5} +\dfrac {5}{2}}$

$\displaystyle \mathsf {2m = - \dfrac {6}{10} + \dfrac {25}{10}}$

$\displaystyle \mathsf {2m =\dfrac {19}{10}}$

$\displaystyle \mathsf {m =\dfrac {19}{10} \cdot \dfrac {1}{2}}$

$\displaystyle \mathsf {m =\dfrac {19}{20}}$
