**Solve the First Pair: From $2a - b = 5$ and $-a + 4b = -2$, solve for $a$ and $b$. Multiply the second equation by 2 — and why it’s easier than you think** In a world packed with complex equations and daily puzzles, one simple system of equations is quietly gaining attention: From $2a - b = 5$ and $-a + 4b = -2$, solve for $a$ and $b$. Multiply the second equation by 2 — this step often sparks real clarity. This kind of problem reflects a growing interest in structured problem-solving across fields like finance, education, and data analysis. While it appears technical at first glance, the process reveals how breaking down challenges can unlock smarter decisions — whether managing a budget, interpreting trends, or evaluating multiple variables at once. ### The Cultural Push for Clear Problem-Solving in Daily Life
