The answer is 9.
You solve it as:
2x-9=x
2x-x=9
x=9
2-9= 4-2=2
imconfuse with this stuff. im just sayin it as it is in the book. its my homework.
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
twice a number can be 2x and six less than it is 2x-6.
The sum of a number times 3 and 27 is greater than or equal to 15.
Given a number N, you would have: 2*N - 5
Nine less than five times a number is equal to -30
um, 9.
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
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
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.
It is when the number is -5. I'm so smart.
9+4x=2x-1 2x=-10 x=-5
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
