Let the number be x.
According to the given information, the sum of 38 and twice the number is 124.
So we can write the equation as:
38 + 2x = 124
Subtracting 38 from both sides, we get:
2x = 124 - 38
2x = 86
Dividing both sides by 2, we get:
x = 43
Now, we can substitute x = 43 into the expression -2x - 5:
-2(43) - 5 = -86 - 5 = -91
Therefore, the value of -2x - 5 is -91.
The correct answer is option B: -91.
