Understanding Linear Equations and Functions

The video tutorial introduces linear functions and equations, explaining key terms such as variables, constants, and coefficients. It guides viewers on recognizing linear equations by identifying terms and their powers. Examples are provided to differentiate between linear and non-linear equations. The tutorial also covers solutions to linear equations, discussing conditional, contradiction, and identity equations.
