In mathematics a linear equation is an equation that may be put in the form where are the variables or unknowns and are the coefficients which are often real numbersThe coefficients may be considered as parameters of the equation and may be arbitrary expressions provided they do not contain any of the variablesTo yield a meaningful equation the. This is also true for a linear equation of order one with non-constant coefficients. The main idea here is that we solve one of the equations for one of the unknowns and then substitute the result into the other equation.
