The linear inequalities require an understanding of some important formulae. In general, the linear equation exists in the form – for example, 8a + 2 = 18, where 8 and 2 are integers and x is a variable, indicating the presence of only one variable. Hence, for solvi...
Linear Equation of One Variable An equation of one variable where the variable have unit power is called a linear equation(LE).Example:2x-3=8 and 3x-10=0 are both linear equations.2x2=8 and 3x+√x=14 are not linear equations.Remember:In linear equation there is no ...
where the subscript of the b's and the first subscript of the a's designate the equation, while the subscript of the x's and the second subscript of the a's designate the variable. We define the m × n matrix A of coefficients as the m-row by n-column array A=[a1,1a1,2a1,3...
