Solution

$\begin{matrix} m & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13 m + 10 & 11 & 12 & 13 & 14 & 15 & 16 & 17 & 18 & 19 & 20 & 21 & 22 & 23 \end{matrix}$

The given equation is $m + 10 = 16$ .

By analysing the table above, we can understand that only m=6 satisfies the given equation.

$∴ m = 6$ is the solution.
