1. State what you need to solve for.

This is the question.
One-third of a number is 5 less than half of the same number. What is the number?
(I always get confused on word problems) This is what I think. I don't know for sure.
1. The number must be found.
2. The unknowns are x.
3. 1/3x=5-(1/2)x
4. If this is the correct formula, this is how I solved it.
6((1/3)x + (1/2)x) = (5)6
6(1/3)x + 6(1/2)x = 30
2x + 3x =30
5x =30
x =6
5. Check. (1/3)(6)=5-(1/2)(6)
2=5-3
2=2
Is this the correct formula for this problem? I think I solved it correctly. I just went back to school, so this is actually one of my first word problems I solved correctly, if it is correct?
Thanks alot for checking it. :)
