To find the value of X, we first need to set up an equation.
Let's assume the number is X.
According to the given information, the sum of 38 and twice the number X is 124, which can be expressed as:
38 + 2X = 124
Now, let's solve this equation to find the value of X:
Subtracting 38 from both sides:
2X = 124 - 38
2X = 86
Dividing both sides by 2:
X = 43
Therefore, the value of X is 43.
Now, let's find the value of -2X - 5:
-2X - 5 = -2(43) - 5
= -86 - 5
= -91
So, -2X - 5 is equal to -91.
