the difference when 7 less than a number is subtracted from twice the number is 12. what it the number?

Thanks for helping out

2n - n - 7 = 12

n = 12 + 7

n = 19

Let's use variables to represent the number. Let's say the number is 'x'.

According to the problem, "7 less than a number" can be written as 'x - 7'.

"Twice the number" can be written as '2x'.

The problem states that when "7 less than a number is subtracted from twice the number", it equals 12:

2x - (x - 7) = 12

To solve this equation, first simplify the expression inside the parentheses:

2x - x + 7 = 12

Combine like terms:

x + 7 = 12

Now, isolate the variable by subtracting 7 from both sides of the equation:

x = 12 - 7

x = 5

Therefore, the number is 5.

To solve this problem, we can translate the given information into an equation. Let's assume the number is represented by the variable "x".

According to the problem, "7 less than a number" can be written as (x - 7). "Twice the number" can be written as 2x.

So, the equation can be formed as follows:

2x - (x - 7) = 12

To solve the equation, follow these steps:

1. Distribute the negative sign to (x - 7):

2x - x + 7 = 12

2. Combine like terms:

x + 7 = 12

3. Move 7 to the other side by subtracting 7 from both sides of the equation:

x = 12 - 7

4. Simplify:

x = 5

Therefore, the number is 5.
