$13 {x}^{3}$

Explanation:

They are both have a common term of ${x}^{3}$ which makes this problem very easy to simplify:

Just simply add the numbers and then it is simplified. Do this when the common term of $x$, ${x}^{2}$, ${x}^{3}$, etc, is the same.

$6 + 7 = 13$

$\therefore$ $\to 6 {x}^{3} + 7 {x}^{3} = 13 {x}^{3}$
