The sum of 38 and twice a number X is 124. What is negative 2X -5.
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.
To find the value of negative 2X - 5, we first need to find the value of X using the given information.
We are given that the sum of 38 and twice a number X is 124. This can be written as the equation:
38 + 2X = 124
To isolate X, we can subtract 38 from both sides of the equation:
2X = 124 - 38
Simplifying this gives:
2X = 86
To solve for X, we can divide both sides of the equation by 2:
X = 86 / 2
Simplifying further:
X = 43
Now that we have the value of X, we can substitute it into the expression -2X - 5:
-2(43) - 5
Evaluating this expression gives:
-86 - 5
Which simplifies to:
-91
Therefore, the value of -2X - 5 is -91.
To find the value of negative 2X - 5, we first need to solve for the number X.
Let's translate the given information into an equation: The sum of 38 and twice a number X is 124.
This can be written as:
38 + 2X = 124
To solve for X, we need to isolate it on one side of the equation. We can do this by subtracting 38 from both sides:
38 + 2X - 38 = 124 - 38
2X = 86
Now, divide both sides of the equation by 2 to solve for X:
2X/2 = 86/2
X = 43
Now that we have found the value of X as 43, we can substitute this value into the expression -2X - 5:
-2(43) - 5 = -86 - 5
= -91
Therefore, the value of negative 2X - 5 is -91.
