A mathematical statement that indicates that the value of the LHS is equal to the value of the RHS is called an equation.

Lesson Demo
• 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.
