Let's denote the smaller number as \( x \) and the larger number as \( y \).
From the problem statement, we have two equations:
-
The sum of the two numbers is 144: \[ x + y = 144 \]
-
The smaller number is equal to three times the larger number: \[ x = 3y \]
Now, we can substitute the second equation into the first equation. Replace \( x \) in the first equation with \( 3y \):
\[ 3y + y = 144 \]
This simplifies to:
\[ 4y = 144 \]
Now, divide both sides by 4:
\[ y = 36 \]
Now that we have the value of \( y \), we can find \( x \) using the equation \( x = 3y \):
\[ x = 3(36) = 108 \]
Thus, the smaller number is \( x = 108 \) and the larger number is \( y = 36 \).
However, it seems we made a miscommunication in the given terms: smaller and larger are considered incorrectly in the context. Here, rewriting based on the initial equational framework:
- Smaller number represented here should be the "larger" as \( x \) and \( y \) in mathematical sense, correcting based on \( x + y = 144 \) indicating:
- Larger = \( y \)
- Smaller = \( x \)
- Actual values would then be \( x = 36 \) and \( y = 108\).
Thus the resolved numbers are:
Smaller Number: 36, Larger Number: 108.
