We are given that the sum of two numbers is 24. If "x" and "y" are the two numbers then we have that:


x+y=24

We are also given that one number is three times the other, this is expressed as:


x=3y

Now, we substitute the value of "x" from the second equation in the first equation:


3y+y=24

Now, we add like terms:


4y=24

Now, we divide both sides by 4:


y=(24)/(4)=6

Therefore, the first number is 6. Now, we substitute the value of "y" in the second equation:


\begin{gathered} x=3(6) \\ x=18 \end{gathered}

Therefore, the other number is 18.
