Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will focus on solving a linear equation with a single variable, specifically the equation -0.58n = 0.928. We will break down the solution process into manageable steps, making it easy for readers to understand and apply.

Understanding the Equation

Before we dive into solving the equation, let's take a closer look at what it represents. The equation -0.58n = 0.928 is a linear equation with a single variable n. The equation states that the product of -0.58 and n is equal to 0.928. Our goal is to isolate the variable n and find its value.

Step 1: Isolate the Variable

To solve the equation, we need to isolate the variable n. We can do this by dividing both sides of the equation by the coefficient of n, which is -0.58. This will give us the value of n that satisfies the equation.

# Import necessary modules
import math

# Define variables
a = -0.58
b = 0.928

# Divide both sides of the equation by a
n = b / a

Step 2: Simplify the Expression

Now that we have isolated the variable n, we can simplify the expression by evaluating the division. This will give us the final value of n.

# Simplify the expression
n = b / a
print(n)

Step 3: Check the Solution

Once we have found the value of n, we need to check if it satisfies the original equation. We can do this by plugging the value of n back into the original equation and verifying that it is true.

# Check the solution
if a * n == b:
    print("The solution is correct")
else:
    print("The solution is incorrect")
