Question: The average of $ 2x + 4 $, $ 5x - 3 $, and $ 3x + 7 $ is 20. What is the value of $ x $?
["The average of $2x + 4$, $5x - 3$, and $3x + 7$ is 20. What is the value of $x$? \nA simple algebra question gaining quiet attention for its balance of logic and real-world relevance in digital spaces. As curious learners explore patterns in data and equations, this problem surfaces quietly across mobile devices—especially among students, educators, and professionals seeking clarity in math basics.", "---", "### Why This Problem Is Trending Now", "In a world increasingly shaped by data-driven decisions, math problems like this mirror practical challenges in finance, personal budgeting, and algorithm learning. The rise in interest stems from a growing desire to understand how averages inform real-life metrics—from monthly expenses to performance tracking. Despite being an equation based on $x$, the question reflects a mindset tied to transparency, problem-solving, and smart estimations that resonate with US users navigating economic complexity.", "---", "### How to Solve It: A Clear Step-by-Step Explanation", "To find $x$, begin by applying the definition of average: sum of values divided by the number of terms. The three expressions are: \n$2x + 4$, $5x - 3$, and $3x + 7$.", "Add them together: \n\[\n(2x + 4) + (5x - 3) + (3x + 7) = (2x + 5x + 3x) + (4 - 3 + 7) = 10x + 8\n\]", "Since there are three values, divide by 3: \n\[\n\ ext{Average} = \frac{10x + 8}{3}\n\]", "Set this equal to 20: \n\[\n\frac{10x + 8}{3} = 20\n\]", "Multiply both sides by 3:"]
