Simple Equations 

(NCERT Exercise 4.4)

Important Points:
❶ An equation which has only one variable whose power is one is called a SIMPLE EQUATION.

❷ In a simple equation keeping only the variable in the LHS of the equation and moving the constant to RHS (right hand side) is called the method of TRANSPOSITION.

❸ Rules for method of Transposition are:

1. A positive constant in the LHS becomes a negative constant when it is taken to the RHS and vice versa.
2. A negative constant in the LHS becomes a positive constant when it is taken to the RHS and vice versa.
3. The coefficient of the variable in tbe LHS becomes t.he multiplicative inverse when it is taken to the RHS :and vice versa.

❹ An equation remains the same if the LHS and the RHS are interchanged.
