	 	| Question : |  
	 		| What is a 'Conditional Equation' ? |  
	 	| Answer :
 |  
	 		    | An equation 
                  is a symbolic statement that two quantities are equal in value. 
                  When an equation is true for a values of the letters, it is 
                  an identity, for example : 4a + 9a = 13a. However, when this 
                  is not the case, it is known as a Conditional Equation. |  
	 		    | For 
                  Example : |  
	 		| x + 5 = 3x - 3. In this case the formula is true only if x = 4. Only then 4 + 5 = 12 - 3 or 9 = 9. |  |
