Introduction
Linear equations are a fundamental concept in mathematics, and they play a crucial role in various fields such as physics, engineering, economics, and computer science. In this article, we will explore the concept of linear equations, how to write them, and how to solve them. We will also use a real-life example to illustrate the concept.
What is a Linear Equation?
A linear equation is an equation in which the highest power of the variable(s) is 1. In other words, it is an equation that can be written in the form:
ax + b = c
where a, b, and c are constants, and x is the variable.
Understanding the Components of a Linear Equation
Let's break down the components of a linear equation:
- a: The coefficient of the variable x. It is a constant that multiplies the variable x.
- b: The constant term. It is a constant that is added to the product of the coefficient and the variable.
- c: The constant term on the right-hand side of the equation. It is the value that the equation is equal to.
Writing a Linear Equation
To write a linear equation, we need to follow these steps:
- Identify the variable: Determine the variable that we want to solve for.
- Determine the coefficient: Determine the coefficient of the variable.
- Determine the constant term: Determine the constant term on the right-hand side of the equation.
- Write the equation: Write the equation in the form ax + b = c.

Let's use the example given in the problem statement to illustrate the concept of linear equations.
Given Information
- Y = 12 when X = 6
Unknown Information
- The value of Y when X = 6
Linear Equation
To write a linear equation, we need to follow the steps outlined above. Let's identify the variable, determine the coefficient, and determine the constant term.
- Variable: Y
- Coefficient: 1 (since the highest power of Y is 1)
- Constant Term: 12 (since Y = 12 when X = 6)
Linear Equation
Y = 1X + 12
Simplifying the Equation
To simplify the equation, we can rewrite it in the form Y = X + 12.
Solving for Y
Now that we have the linear equation, we can solve for Y when X = 6.
Substituting X = 6 into the Equation
Y = 6 + 12
Simplifying the Equation
Y = 18
Therefore, the value of Y when X = 6 is 18.
