The answer is 9.
You solve it as:
2x-9=x
2x-x=9
x=9
imconfuse with this stuff. im just sayin it as it is in the book. its my homework.
Given a number N, you would have: 2*N - 5
To find 2 less than twice a number, you would first multiply the number by 2 and then subtract 2 from the result. In mathematical terms, this can be represented as 2x - 2, where x is the number in question. For example, if the number is 5, then 2 less than twice the number would be 2(5) - 2 = 10 - 2 = 8.
2x-3 , where x is the number referred to in the question
x / (2y - 7)
um, 9.
Nine less than twice a number equals the same number increased by four?
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.

Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
It is when the number is -5. I'm so smart.
One less than nine or 9-1 would equal 8.
Nine greater than 6 is equal to 15. Therefore, 9 less than 15 is 6.
9+4x=2x-1 2x=-10 x=-5
it is 30
The Answer:You are implying that 2x - 9 = 31. Add 9:2x = 40Divide by 2:x = 20Therefore, the number must be 20.
