In this video we will learn about the basics of Linear Equations in two variables.

Some important points to revise from the chapter are: • An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in ...

This equation is in the standard form of a linear equation: A x + B y = C, where A, B, and C are constants. The variable x is raised to the power of 1. The variable y is raised to the power of 1. The ...

Matching linear equations with their corresponding graphs is a fundamental skill in algebra and a crucial stepping stone for ...

Sometimes in mathematics we like to use letters to represent numbers. The ‘value’ of these letters can change according to certain rules or conditions we are given – hence we can call them variables.

We give the existence and the analytic form of the solutions to the linear fractional differential equations in which coefficients are bounded function on [0, b]. The method which is used is based on ...
