["Title: Solve Linear Equation ( 50x + 2000 = 80x ): Step-by-Step Explanation", "---", "Introduction", "Linear equations form the foundation of algebra and are essential for solving real-world problems in science, economics, and engineering. One common type of linear equation involves isolating a variable on one side. In this article, we explore and solve the equation:
\n[
\nC(x) = R(x) \quad \ ext{where} \quad 50x + 2000 = 80x
\n]
\nWe show how to solve for ( x ) efficiently, explaining each step clearly for better understanding.", "---", "Understanding the Equation", "The equation ( 50x + 2000 = 80x ) equates two expressions:
\n- ( R(x) = 80x ): a linear revenue or growth function often representing increasing velocity or cost over time.
\n- ( C(x) = 50x + 2000 ): a linear cost or fixed cost function, typically including a flat fixed cost (2000) plus variable costs growing linearly.", "The goal is to find the value of ( x ) where costs equal revenue — a key point in business analysis and break-even modeling.", "---", "Step-by-Step Solution", "We solve the equation algebraically by isolating ( x ).", "### Step 1: Move all terms with ( x ) to one side", "Subtract ( 50x ) from both sides:
\n[
\n50x + 2000 - 50x = 80x - 50x
\n]", "This simplifies to:
\n[
\n2000 = 30x
\n]", "### Step 2: Solve for ( x )", "Divide both sides by 30:
\n[
\nx = \frac{2000}{30}
\n]", "Simplify the fraction:
\n[
\nx = \frac{200}{3} \approx 66.67
\n]", "---", "Interpretation of the Result", "The solution ( x = \frac{200}{3} ) means that when the variable ( x ) reaches approximately 66.67, the cost ( C(x) = 50x + 2000 ) equals the revenue ( R(x) = 80x ).", "This is a break-even point, where income matches expenses. In practical terms, if ( x ) represents units produced or time elapsed, producing about 66.67 units results in no profit or loss.", "---", "Graphical Insight", "Plotting ( y = 50x + 2000 ) and ( y = 80x ) helps visualize intersection:", "- Line with slope 50 (C) starts higher at ( (0, 2000) ) and increases slowly.
\n- Line with slope 80 (R) starts at the origin and rises faster.", "They intersect exactly where ( x = \frac{200}{3} ), confirming our algebraic result.", "---", "Conclusion", "The equation ( 50x + 2000 = 80x ) represents a fundamental linear relationship, useful in cost-revenue analysis. By isolating ( x ), we found the break-even point efficiently. Understanding such equations allows precise decision-making in business and math-based modeling.", "---", "SEO Tips for This Article:", "- Use long-tail keywords like “solve linear equation 50x + 2000 = 80x step by step”
