Solving the Equation: 60 + x = 0.5(200 + x)

Understanding how to solve equations is fundamental in algebra, and today we’ll tackle the equation 60 + x = 0.5(200 + x) step-by-step. Whether you’re a student learning basic algebra, a teacher explaining problem-solving techniques, or someone brushing up on math fundamentals, this article will guide you through solving linear equations with clear explanations and practical insight.

Step-by-Step Solution

Understanding the Context

The given equation is:
60 + x = 0.5(200 + x)

Step 1: Expand the Parentheses

First, distribute the 0.5 on the right-hand side:
60 + x = 0.5 × 200 + 0.5 × x
60 + x = 100 + 0.5x

Step 2: Rearrange Terms with x on One Side

Subtract 0.5x from both sides to gather like terms:
60 + x – 0.5x = 100
60 + 0.5x = 100

Step 3: Isolate the Constant

Subtract 60 from both sides:
0.5x = 100 – 60
0.5x = 40

Key Insights

Step 4: Solve for x

Divide both sides by 0.5:
x = 40 ÷ 0.5
x = 80


Final Answer

x = 80
