Simplify:

$2[6 + 4{m - 6(7 - \overline{n + p}) + q}]$

$2[6 + 4{m - 6(7 - \overline{n + p}) + q}]$

= $2[6 + 4{m - 6(7 - n - p) + q}]$

= $2[6 + 4{m - 42 + 6n + 6p + q}]$

= $2[6 + 4m - 168 + 24n + 24p + 4q]$

= $2[(6 - 168) + 4m + 24n + 24p + 4q]$

= $2[-162 + 4m + 24n + 24p + 4q]$

= $-324 + 8m + 48n + 48p + 8q$

Hence, $2[6 + 4{m - 6(7 - \overline{n + p}) + q}] = 8m + 48n + 48p + 8q -324$
