Objective:Solve systems of linear equations using elimination Example 1) 3 x + 2 y = 2 -3 x + 2 y = 6 Add the equations 4 y = 8Simplify y = 8/4 = 2 Substitute using y = 2 3 x + 2(2) = 2 3 x + 4 = 2Simplify ...
Here I've got two. Can I get rid of one of these variables in the system, just as I'd have gotten rid of the −6 in the equation? Looking at the system of equations they've given me, I see that I've got a +y in the first line, and a −y in the second line. If I...
Differential equations are equations where rates of change occur with respect to variables. Learn how to solve systems of linear differential...

In this paper we consider the systematic use of block elimination in solving sparse symmetric positive definite systems of equations that arise in the application of finite element methods to two dimensional elliptic and parabolic problems. Given such an N by N system of equations, it has been sh...
the method we'll use to convert systems to this upper triangular form, using the "row operations" (that is, the multiplying through, the dividing through, and the adding down) that we saw when we learned the "addition/elimination method" of solving systems of equations on the previous page...
