Calculate the value of $(\mathrm{x}+\mathrm{y}+\mathrm{z})$ based on the following parameters for $\mathrm{Al}{\left({\mathrm{BH}}_4\right)}_3$

$x$ = Number of 3c–2e⁻ (three-center, two-electron) bonds

$y$ = Number of 2c–2e⁻ (two-center, two-electron) bonds

$z=(n_1+n_2)$, where the hybridization of Aluminum (Al) in the molecule is ${\mathrm{sp}}^{n_1}{d}^{n_2}$.
