Lesson Objective

This lesson shows you the basics that you need to know when solving linear
equations.

About This Lesson

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.

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.

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.

x +2 = 3

The

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

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

Tip #4

The math video shows some shortcuts that can be
used for solving linear equations quickly. You may want to
