# Solving Linear Equation - Part 1

Lesson Objective
This lesson shows you the basics that you need to know when solving linear equations.
If you are asked to find the value of x in the equation:
x + 2 = 3

You can immediately solve the equation by letting x = 1. This is because both sides of the equation must be equal to 3 for this equation to remain true.

Now, this lesson shows the basics that you need to know when solving linear equations. These basics are very useful when it comes to solving more complicated equations.

# Study Tips

Tip #1
For linear equations, the variable (or unknown) that you need to find has only one value (i.e. one correct answer)
Tip #2
An equation has 2 sides. One is called Left Hand Side (LHS) and another is called Right Hand Side (RHS). For example, consider the equation:

x +2 = 3

The LHS is x+2 and the RHS is 3.
Tip #3
Realize the importance of the equal sign (=) in an equation. This sign means that both sides of the equation must balance up each other.

So, whatever is added in the LHS must be equally be added in the RHS
