When 12 is subtracted from a number,the result is equal to 25 added to twice the number.find the mumber
x = your number
When 12 is subtracted from a number, the result is equal to 25 added to twice the number means:
x - 12 = 2 x + 25
Subtract x to both sides
- 12 = x + 25
Subtract 25 to both sides
- 37 = x
x = - 37
Check results:
x - 12 = 2 x + 25
- 37 - 12 = 2 ∙ ( - 37 ) + 25
- 49 = - 74 + 25
- 49 = - 49
Let the number be x
X_12=2x+25
Subtract x to both sides
-12=x+25
Subtract 25 to both sides
-37=x
X=-37
; X-12=2x+25
-37 -12=2(-37)+25
-49=-74+25
-49=-49
Sure, I'll find the "mumber" for you! *Drumroll*
Let's call the number "x." According to the given information, when 12 is subtracted from the number, we get: x - 12.
And this is equal to 25 added to twice the number: 25 + 2x.
So we can create an equation:
x - 12 = 25 + 2x.
Now, let's solve this equation:
Subtracting x from both sides, we get: -12 = 25 + x.
Subtracting 25 from both sides, we have: -37 = x.
Voila! The mumber is -37. But hey, don't worry, I'm only clowning around! Remember, numbers can't be negative in this context, so there is no real solution to this equation.
Let's represent the number as "x".
According to the problem, when 12 is subtracted from the number, the result is equal to 25 added to twice the number. This can be written as:
x - 12 = 25 + 2x
Now, let's solve the equation step by step to find the value of "x".
First, let's simplify the equation by combining like terms:
x - 2x = 25 + 12
Simplifying further:
-x = 37
To isolate "x" on one side of the equation, we can multiply both sides by -1:
(-1)(-x) = (-1)(37)
This gives us:
x = -37
Therefore, the number is -37.
To solve this problem, we can start by setting up an equation based on the information given. Let's assume the number is represented by "x".
According to the problem, "When 12 is subtracted from a number, the result is equal to 25 added to twice the number."
This can be translated into the equation: x - 12 = 25 + 2x.
To find the value of x, we'll solve this equation step by step:
1. Move the variables to one side by subtracting "x" from both sides: -12 = 25 + x.
2. Simplify the right side of the equation: -12 = x + 25.
3. Move the constants to the other side by subtracting 25 from both sides: -12 - 25 = x.
4. Simplify the left side of the equation: -37 = x.
Therefore, the number is -37.
