If you add two-thirds of a number to the number itself, you get 40. What is the number?
I do not know how to set it up?
2/3n + n = 40
Solve for n.
I don't know but thak you sooooooooooo much for helping me on my mixed #'s!!!!!!!! Good Luck!!!!!!

To solve the equation 2/3n + n = 40, you need to combine like terms.
First, you need to find a common denominator for the fractions. In this case, the common denominator is 3, so you can rewrite the equation as (2n/3) + (3n/3) = 40.
Next, add the fractions together: (2n/3) + (3n/3) = (2n + 3n) / 3 = 5n/3.
Now the equation becomes 5n/3 = 40. To isolate n, multiply both sides of the equation by 3 to eliminate the denominator: 3 * (5n/3) = 3 * 40.
This simplifies to 5n = 120.
Finally, divide both sides of the equation by 5 to solve for n: 5n/5 = 120/5, which gives n = 24.
Therefore, the number is 24.
