Question: A hydrologist models groundwater flow through three aquifers, measuring flow rates of $ 3x+2 $, $ 5x-4 $, and $ 4x+1 $ liters per minute. If the average flow rate is 15 liters per minute, what is the value of $ x $?

**Understanding Groundwater Models: Solving the Flow Rate Mystery** Groundwater systems are among Earth’s most hidden yet vital resources—how they move through layered rock and sediment determines water availability for wells, farms, and cities across the United States. Recent interest in sustainable water management has amplified public curiosity about how hydrologists analyze these underground flows. When scientists model aquifer contributions using three flow rates—$3x+2$, $5x-4$, and $4x+1$ liters per minute—and calculate an average of 15 liters per minute, uncovering the true value of $ x $ reveals fundamental insights into subsurface water dynamics. This isn’t just a math problem—it’s a window into how professionals predict water movement and support informed policy. ### Why Groundwater Flow Models Like This Are Gaining Attention Across the U.S., growing demands on freshwater resources have sparked heightened awareness of groundwater sustainability. Climate variability and population shifts increase the need for precise modeling to balance usage and conservation. Questions about how hydrologists assess aquifer performance—especially through typical polynomial expressions like $3x+2$—reflect a broader public interest in transparent, data-driven environmental science. People recognize these models influence everything from drinking water security to agricultural planning, making this kind of problem not only intellectually engaging but practically relevant.
