    Help!

    Hi guys! I have one math problem, I cannot solve. Please help me out. Here's the question:

    "How can the number 39 be divided into two parts in order that the sum of 2/3 of one part and 3/4 of the other part is 28?"

    I think you need to make some equation to solve this problem, but I cannot make a proper equation, please help me out.

    Let one of the numbers be x then the other is 39-x.

    Then we are told that:

    \frac{2}{3}x+\frac{3}{4}(39-x)=28

    which you can now solve for x.

    x=15
