Question

( M + 2,7) . 3,9 - 48,6 = 9,9

Answer 1

Resposta:

( M + 2,7) . 3,9 - 48,6 = 9,9

3,9M + 10,53 - 48,6 =9,9

3,9M=9,9 - 10,53 + 48,6

3,9M = 47,97

M=47,97/3,9

M=12,3

Answer 2

$\LARGE\displaystyle{}\left(m + 2,7\right) \times 3,9 - 48,6 = 9,9 \\\\ \LARGE\displaystyle{}3,9m + 10,53 - 48,6 = 9,9 \\\\ \LARGE\displaystyle{}3,9m - 38,07 = 9,9 \\\\ \LARGE\displaystyle{}3,9m = 9,9 + 38,07 \\\\ \LARGE\displaystyle{}3,9m = 47,97 \\ \\ \LARGE\displaystyle{}3,9m \div 3,9 = 47,97 \div 3,9 \\ \LARGE\displaystyle{}m = 47,97 \div 3,9 \\ \\ \LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ m = 12,3}}}\end{gathered} }$
