seven less than a number is 14 more than 2 times that number. what is that number
n - 7 = 14 + 2n
Seven less times a number is 15
To solve this problem, we need to express the given statement algebraically.
Let's represent the unknown number as "x".
The statement "seven less than a number" can be written as "x - 7".
The statement "14 more than 2 times that number" can be written as "2x + 14".
Now we have the equation:
x - 7 = 2x + 14
To find the value of x, we can solve this equation.
Moving all the terms with x to one side, we get:
x - 2x = 14 + 7
Simplifying, we have:
-x = 21
Dividing both sides by -1, we get:
x = -21
Therefore, the number is -21.
