Understanding the Equation: 2(w + 2w) = 36 Implies 6w = 36 → w = 6

Solving linear equations step-by-step is a fundamental skill in algebra, essential for students, educators, and anyone working with mathematical reasoning. One common example is the equation 2(w + 2w) = 36. This equation appears simple but serves as a perfect teaching example to demonstrate how algebraic manipulation leads to a solution.

Breaking Down the Equation

Start with the original equation:
2(w + 2w) = 36

Understanding the Context

First, simplify inside the parentheses. Combine like terms—here, w and 2w:
w + 2w = 3w
So the equation becomes:
2(3w) = 36

Now apply multiplication:
6w = 36
This transformation reflects the distributive property — multiplying 2 by 3w gives 6w.

Solving for w

To isolate w, divide both sides by 6:
6w ÷ 6 = 36 ÷ 6
w = 6

Why This Equation Matters

Understanding how to simplify and solve equations like 2(w + 2w) = 36 builds strong algebraic intuition. This step-by-step approach helps recognize patterns, apply properties of equality (like division or multiplication over both sides), and confirm solutions — all crucial skills for advanced math topics including functions, systems of equations, and real-world problem-solving.
