Systems of Linear Equations - Department of Mathematics
Systems of Linear Equations 0.1 De nitions Recall that if A2Rm n and B2Rm p, then the augmented matrix [AjB] 2Rm n+p is the matrix [AB], that is the matrix whose rst ncolumns are the columns of A, and whose last p columns are the columns of B. Typically we consider B= 2Rm 1 ’Rm, a column vector.

math.mit.eduLet me admit right away—most linear systems are not so easy to solve. In this example, the first equation decided x 1 = b 1. Then the second equation produced x 2 = b 1 + b 2. The equations can be solved in order (top to bottom) because A is a triangular matrix. Look at two specific choices 0,0,0 and 1,3,5 of the right sides b 1,b 2,b 3: b ...
