How to Solve Simple Equations? (Part- 1) - Exercise 4.4 of 3 (ii,iii)

Introduction:
In mathematics, an equation is a statement that asserts the equality of two expressions. In simple terms, it is a statement that shows that two things are equal. Solving equations involves finding the value of the variable that makes the equation true. In this article, we will discuss how to solve simple equations.

Steps to solve simple equations:
To solve simple equations, follow these steps:
- Step 1: Simplify both sides of the equation by performing any necessary operations
- Step 2: Get the variable on one side of the equation by adding or subtracting the same value to both sides of the equation
- Step 3: Simplify both sides of the equation
- Step 4: Check the solution by substituting the value of the variable back into the original equation

Example:
Let's solve the equation 2x + 3 = 9.
- Step 1: Simplify both sides of the equation by subtracting 3 from both sides, we get 2x = 6
- Step 2: Get the variable on one side of the equation by dividing both sides of the equation by 2, we get x = 3
- Step 3: Simplify both sides of the equation, we get 2(3) + 3 = 9
- Step 4: Check the solution by substituting the value of the variable back into the original equation, we get 2(3) + 3 = 9 which is true.

Exercise 4.4 of 3 (ii,iii):
In exercise 4.4 of 3, we are given some equations to solve. To solve these equations, we need to follow the steps mentioned above.

Conclusion:
Solving simple equations is an important concept in mathematics. It helps in solving real-world problems and is used in various fields such as science, engineering, and economics. By following the steps mentioned above, we can easily solve simple equations.
