Solve a Linear Equation by Transposition Method First let’s a review what is an equation. In mathematics, an equation is a mathematical expression where two sides of expression are connect to an “equality sign”. In this tutorial we will learn how to solve a linear equation in one variable by transposition method. This method is […]
Read More →Linear Equations – An Overview A linear equation is an algebraic equation with an equality sign and highest exponent of the variable is 1. Equality sign (=) divides the equation into two sides such as LHS and RHS. In a linear equation highest exponent of the variable is 1. The standard form of a linear […]
Read More →What is an Equation Definition: An equation is a mathematical statement with an ‘equality’ sign between two algebraic expression. The equality sign shows that the value of the expression to the left of the side (LHS or left hand side) is equal to the value of the expression to the right hand side (RHS or […]

These basic operations are used in algebra with numbers or letters or combination of both. A number multiplied by a variable, a number or variable is called a term. An expression is combination of such terms. Example: In […]
