Answer:

t=\frac{u}{2} would complete the system

Number is 36

Step-by-step explanation:

Let t = the tens digit, u = the units digit

We have the sum of the two digits of a number is 9

          t + u = 9

We also have the tens digit is one-half the units digit

       t=\frac{u}{2}

Substituting

            \frac{u}{2}+u=9\\\\\frac{3u}{2}=9\\\\u=6

               t + 6 = 9

               t = 3

So the number is 36.
