Solving the Equation 3n - 12 24: A Comprehensive Guide

Understanding and solving equations is a fundamental skill in mathematics. This article delves into the step-by-step process of solving the equation 3n - 12 24, providing a clear explanation of each stage of the solution process. Whether you are a student, a teacher, or anyone interested in enhancing your problem-solving skills in algebra, this detailed guide aims to help you grasp the underlying concepts.

Simplifying the Equation

The given equation is 3n - 12 24. Here, we need to find the value of n. Let's start by breaking down the equation into simpler steps.

Step 1: Isolate the Variable Term

First, we want to isolate the term with the variable, n. To do this, we need to add 12 to both sides of the equation to get rid of the -12 on the left side.

3n - 12 12 24 12

3n 36

Step 2: Solve for the Variable

Now that we have simplified the equation to 3n 36, the next step is to solve for n. To do this, we need to divide both sides of the equation by 3.

3n/3 36/3

n 12

Verification

To ensure our solution is correct, we can substitute the value of n back into the original equation:

3n - 12 24

3(12) - 12 24

36 - 12 24

24 24

The equation holds true, confirming that our solution is correct.

General Techniques for Solving Equations

When solving equations, it is essential to follow a systematic approach. Here are some general techniques that can be applied to a wide range of equations:

Isolating the Variable Term

The primary goal in solving an equation is to isolate the variable term. This involves moving all terms with the variable to one side of the equation and all constant terms to the other side.
