Solving Equations

An equations is a combination of one or more terms separated with equal to "=" symbol. Terms can be numerical,alphanumerical, expression etc.

 

Different type of equations.

 

1.) equations which have solution : In these types of equation we can find the value of variable like a, b, c.

 

Examples:

 

a.) 5x + y = 12 , 7x – 2y = 21

 

b.) 2a – 3b = 6 , 5a + b = 10

 

After solving these two equation we will get the value of x and y.

 

A number which satisfies the given equation is called a solution or root of that .‘Satisfying the equation’ means that if the variable (literal) involved in this is replaced by the number, then both sides of that become equal.The process of finding the particular value of the variable (literal) which makes both sides of the equation equal is called solving the equation. Below are rules that need to be followed in solving equations.
