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