A sample of novel verbal problems which can be solved by using systems of linear equations with free variables is presented. The procedure of Gaussian elimination is used to solve the system. (KR)doi:10.1111/j.
Precalculus Module 5: Systems of Equations and Inequalities Search for: Problem Set 35: Solving Systems with Inverses1. In a previous section, we showed that matrix multiplication is not commutative, that is, AB≠BAAB≠BA in most cases. Can you explain why matrix multiplication is commutative...
Precalculus Module 5: Systems of Equations and Inequalities Search for: Problem Set 36: Solving Systems with Cramer’s Rule1. Explain why we can always evaluate the determinant of a square matrix. 2. Examining Cramer’s Rule, explain why there is no unique solution to the system when th...
Two pools are being filled with water. To start, the first pool contains 1900 liters of water and the second pool contains 1440 liters of water. Water is being added to the first pool at a rate of 24.25 liters per minute. Water is being added to the second pool at a r...

To solve the nonlinear system of equations exp(−exp(−(x1+x2)))=x2(1+x21)x1cos(x2)+x2sin(x1)=12 using the problem-based approach, first definexas a two-element optimization variable. Get x = optimvar('x',2); Create the first equation as an optimization equality expression. ...
The value of the known variable is then used to find the value of the unknown variable. 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 tog...
System of integro-differential equationsSolvability criteriaAlgorithmComputational methodThis 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 ...
Intelligent tutoring system (ITS) provides learners with step-by-step problem-solving support through scaffolding. Most ITSs have been developed in the USA
A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 75 pounds. The truck is transporting 55 large boxes and 60 small boxes. If the truck is carrying a total of 4300 pounds in boxes, how much does ea...
