**Expression** is a simple math relationship between a variable and a number. The **variable **is the quantity which can take any value accordingly (usually represented by an **alphabet**). However an **Equation** relates two different expressions with an **‘equality’** sign

**Examples of Expressions:**

For Equations, not only can be it evaluated but also the value of the unknown variable can be found out! There can be a single or multiple solutions for the variable depending on the type of equation.

**Examples of Equation:**

**Example: **Solve 5x – 6 = 2x +15

Here **2 expressions** are combined together to form an **equation**!

**->** 5x- 2x -6 = 15 (Subtract ‘2x’on both sides)

**->** 3x=15+6(Add ‘6’ on both sides)

**->** 3x=21

**->** x=21/3 **->** **x = 7**
