Simplify $ 5x + 6 = 102 $: A Step-by-Step Guide to Solving Linear Equations

Solving algebraic equations is a fundamental skill in math, and simplifying expressions like $ 5x + 6 = 102 $ is essential for students, educators, and lifelong learners alike. Whether you're tackling this equation for homework, preparing for a math test, or building foundational knowledge, understanding how to isolate the variable and solve it step by step is key. In this article, we break down how to simplify and solve the equation $ 5x + 6 = 102 $ clearly and precisely.

Understanding the Context

What Is the Equation $ 5x + 6 = 102 $?

The equation $ 5x + 6 = 102 $ is a linear equation in one variable, where $ x $ represents an unknown number. The goal is to find the value of $ x $ that makes the equation true.

Step 1: Subtract 6 from Both Sides

To isolate the term with $ x $, begin by eliminating the constant on the left side. Subtract 6 from both sides:
$$
5x + 6 - 6 = 102 - 6
$$
Simplify:
$$
5x = 96
$$

Key Insights

This step uses the principle of equality — whatever you do to one side, you do to the other to maintain balance.

Step 2: Divide Both Sides by 5

Now, divide both sides by 5 to solve for $ x $:
$$
rac{5x}{5} = rac{96}{5}
$$
Simplify:
$$
x = 19.2
$$

Since 96 divided by 5 equals 19.2, the solution is $ x = 19.2 $.
