- A mathematical statement that indicates that the value of the LHS is equal to the value of the RHS is called an equation.
- An equation puts a condition on the variable.
- The value for which the equation is satisfied is the solution of the equation.
- The value of the variable in an equation that satisfies the equation, or makes its LHS equal to its RHS, is the solution.
- An equation can contain numbers and variables.
- An equation is said to be algebraic equation if it consists of a variable.
- A single variable equation will have a unique solution.
- An equation that does not have any variable is called a numerical or an arithmetic equation.
- Different numerical values for the variable are substituted in an algebraic equation, and the solution is obtained by using a method called the trial and error method.
If there is no sign of equality between the LHS and the RHS, then it is not an equation.
