-1-|x+5|=-14 is an absolute value equation.  It transforms into two separate equations with different solutions:

First multiply all three terms by -1.  This results in 1 + |x+5| = 14, or |x+5| = 13.

There are two cases here.  The first is when x+5 is already +.  Here the absolute value operator doesn't make any difference:

x+5 = 13.  Subtracting 5 from both sides, we get x = 8.

The second case is when (x+5) is negative.  Applying the absolute value sign produces the result -(x+5).  Note that neg times neg equals pos.  Now write out -(x+5) = 13 and solve for x:  -x - 5 = 13, or x = -18.

The solutions are {-18,8}.
