These so-called MicroDYN items are high quality and designed to assess individual problem solving skills. The items are based on linear structural equations. We describe how this approach was applied to create an assessment item for a collaborative setting with children that implements a simplified ...
We focused on defining the variable, or the unknown quantity, in terms of what is known, then solving for the variable. Oh, and we solved the dreaded algebra train problem. Read Problem-Solving using Linear Equations Lesson Recommended for You Video: Horizontal Line Test | Overview & Function...

For a system of m linear equations with n variables over fractional numbers Q, the Min-Unsatisfy problem can be approximated within a factor of m+1, but the Max-Satisfy problem is NP-hard to approximate within a factor of nδ, for some δ>0 [1], [2]. We notice that the MPSM ...
Elimination Method for Solving Systems of Linear Equations:The elimination method is commonly used to solve systems of linear equations. In this approach, we add the two equations together ensuring that one of the variables cancels the other out during the summation. This result...
This article presents a computational method for solving a problem with parameter for a system of Fredholm integro-differential equations. Some additional parameters are introduced and the problem under consideration is reduced to solving a system of linear algebraic equations. The coefficients and right...
Using your own words, list the steps in the General Strategy for Solving Linear Equations. Answers will vary. Explain why you should simplify both sides of an equation as much as possible before collecting the variable terms to one side and the constant terms to the other side. Solve Equation...
