This video talks about the topic consistent and inconsistent equations for the chapter Pair of Linear Equations in two Variables. While solving a pair of linear equations either we might get a ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

A solution of this system is a list of values for the \(x_i\)s such that when we substitute them into (2.2), the equation holds. A system of linear equations is consistent if it has a solution, ...

A DIFFERENTIAL equation, in its usual form, states an analytical problem with a certain assumption as to the form of the answer. It implies the existence of a dependent variable, capable of being ...
