Starting with the innermost parentheses:
(2+3) = 5
Now we can simplify further:
(3-(2+3)) = (3-5) = -2
Next, let's substitute the simplified value back into the expression:
2+4(-2) = 2 + (-8) = -6
Continuing:
-2(-6) = 12
Finally, substituting back into the original expression:
{-2[2+4(3-(2+3)))]-5} = {-2[-6]-5} = {12-5} = 7
Therefore, the value of the expression is 7.
