What’s the Value of $3x + 2y$ When $x + y = 12$ and $x - y = 4$?

In the quiet hum of online number puzzles and everyday problem-solving, a growing audience is drawn to clear, practical math—especially when it connects to real-world data tracking, such as environmental monitoring or agricultural analytics. One such question gaining gentle traction is: If $x + y = 12$ and $x - y = 4$, what is $3x + 2y$? These types of problems tie into fields like pollen count analysis, where scientists and analysts track separate but correlated variables—like grain dispersion in separate sampling zones. Understanding how to solve them supports better data literacy and real-world reasoning.

This familiar equation surface in both educational content and professional problem-solving contexts, especially in regions with active climate and agriculture sectors. The value of $3x + 2y$ isn’t just a number—it’s a demonstration of how patterns in data unlock deeper insights.

How to Solve: Step-by-Step Breakdown

First, solve for $x$ and $y$ using the two given equations:
$x + y = 12$
$x - y = 4$

Adding both equations eliminates $y$:
$x + y + x - y = 12 + 4$ → $2x = 16$ so $x = 8$

Substitute $x = 8$ into $x + y = 12$:
