How to solve an Equation?

Equation :
 

An equation indicates that the two terms are equal. The two terms are separated by the symbol "=".

For example :

$3 x + 5 = 11$

From the above equation, we can infer that $3 x +5$ and 11 are equal.

Solving an equation :

Step 1:  Add or subtract similar terms.

Step 2: Bring the variables on one side, and number on the other side of the '=' symbol.

Step 3: Multiply or divide the terms, to get the value of the variable.

For Example :

Solve the equation $3 x + 5 = 11$

Step 1: $3 x + 5 = 11$

Step 2: $3 x = 11 - 5$

             $ 3 x = 6$

Step 3:  $3 x = 6$

            $ x = \frac{6}{3}$

            $x = 2$.

The value of x is 2.

This means if we substitute $x = 2$ in the given equation, both the Left-hand side and Right-hand side should be equal.
