Substitution Elimination We will describe each for a system of two equations... unknowns, but each works for systems with more equations and
... 1. Multiply an equation by a non-zero constant. Obviously, this is something that should not be taken literally. What’s really meant is to multiply both sides of an equation by the same non-zero constant to obtain a new equation equivalent to the original equation. 2. Add a multiple of one equation ...

... this inverse on the left, a’ * (a * b) = a’ *(a * c) By the associatively law, (a’ * a ) * b = (a’ * a) * c Since a’ is the inverse of a, a’ * a =e, we have e*b=e*c By the definition of e, b=c Similarly for the right cancellation. ...

... determinant is zero. Whether the determinant is zero depends on how much information is in A. If rows or columns are redundant, then |A| = 0 and there is no unique solution to the system of equations. The determinant of a scalar is simply that scalar.
