Solution

$7 [7 - \{3 - 14 + (15 \times 7 o f 12 - \bar{17 \times 12 - 4})\}] = 7 [7 - \{3 - 14 + (15 \times 7 o f 12 - \bar{204 - 4})\}]$
$= 7 [7 - \{3 - 14 + (15 \times 7 o f 12 - 200)\}] = 7 [7 - \{3 - 14 + (15 \times 84 - 200)\}] = 7 [7 - \{3 - 14 + (1, 260 - 200)\}] = 7 [7 - \{3 - 14 + 1060\}] = 7 [7 - \{1063 - 14\}] = 7 [7 - 1, 049] = 7 \times (- 1042) = - 7, 294$
Hence, the simplified answer is $- 7, 294 .$
