Simplify: $ 2x + 0.4 = 4.6 $.

Simplify $ 2x + 0.4 = 4.6 $: Step-by-Step Guide to Solving the Equation

Solving a linear equation like $ 2x + 0.4 = 4.6 $ can seem tricky at first, but with the right steps, it becomes simple and straightforward. Whether you're a student learning algebra or just looking to refresh your math skills, understanding how to simplify and solve such equations is essential.

In this article, we’ll break down the process of solving $ 2x + 0.4 = 4.6 $ step-by-step, explain the logic behind each operation, and show how simplifying the equation leads to the correct value of $ x $. We’ll also highlight common mistakes to avoid and why mastering equation solving is valuable in real-world applications.

Understanding the Context

Step 1: Understand the Equation

We start with the equation:
$$
2x + 0.4 = 4.6
$$
This represents a linear relationship where $ 2x $ is increased by $ 0.4 $, resulting in $ 4.6 $. Our goal is to isolate $ x $ and find its value.

Key Insights

Step 2: Eliminate the Constant on the Left Side

To simplify, subtract $ 0.4 $ from both sides of the equation:

$$
2x + 0.4 - 0.4 = 4.6 - 0.4
$$
$$
2x = 4.2
$$

By removing $ 0.4 $, we isolate the term with the variable — a crucial first step in solving linear equations.

Final Thoughts

Step 3: Solve for $ x $

Now that $ 2x = 4.2 $, divide both sides by 2 to isolate $ x $:

$$
x = rac{4.2}{2} = 2.1
$$

This gives the solution:
$$
x = 2.1
$$
