See the entire solution process below:

#### Explanation:

Add $\textcolor{red}{7}$ and subtract $\textcolor{b l u e}{7.4 m}$ from each side of the equation to solve for $m$ while keeping the equation balanced:

$8.4 m - 7 + \textcolor{red}{7} - \textcolor{b l u e}{7.4 m} = 7.4 m - 7 + \textcolor{red}{7} - \textcolor{b l u e}{7.4 m}$

$8.4 m - \textcolor{b l u e}{7.4 m} - 7 + \textcolor{red}{7} = 7.4 m - \textcolor{b l u e}{7.4 m} - 7 + \textcolor{red}{7}$

$1 m - 0 = 0 - 0$

$1 m = 0$

$m = 0$
