Page 6: Decimal Coefficients in Linear Systems

The final page deals with a system of linear equations involving decimal coefficients.

Example: x + 2y + 6z = 3.75 is one of the equations in the system, showcasing how to handle decimal values in linear systems.

Highlight: The solution process demonstrates how to manipulate equations with decimal coefficients without converting them to fractions.

This page emphasizes the importance of precision when working with decimal values in linear systems. It also reinforces the back-substitution technique to find all variable values after solving for one.

(1) 3 x + 4y 12 x (3) 3x + 4y 16 x x чу X =5 > = 4:2 +4y=5 X eingesetzt |-6 = 2 = -1 = 5 = 2 = X 14 = {(61-4)} - 1 2x+4y = 12 1-2x-3y = -10

Page 3: Analyzing Solution Types

This page focuses on analyzing different types of solutions for systems of linear equations.

Definition: A system with "unendlich viele Lsg." (infinitely many solutions) represents a true statement, while "keine Lsg." (no solution) represents a false statement.

Example: 3x - 2y = 0 and 9x - 6y = 0 are shown to have infinitely many solutions.

The page demonstrates how to determine whether a system has infinite solutions, no solutions, or a unique solution. This concept is crucial in understanding the nature of linear systems and their graphical representations.

(1) 3 x + 4y 12 x (3) 3x + 4y 16 x x чу X =5 > = 4:2 +4y=5 X eingesetzt |-6 = 2 = -1 = 5 = 2 = X 14 = {(61-4)} - 1 2x+4y = 12 1-2x-3y = -10

Öffnen

Page 4: Solving Systems with Three Variables

This page introduces systems of equations with three variables, demonstrating more complex problem-solving techniques.

Highlight: The page shows how to solve a system of three equations with three unknowns using elimination and substitution methods.

Vocabulary: "Rückwärts einsetzen" means "back-substitution," a technique used to find values for all variables after solving for one.

The solutions are presented step-by-step, allowing students to follow the process of eliminating variables and solving for each unknown systematically.

(1) 3 x + 4y 12 x (3) 3x + 4y 16 x x чу X =5 > = 4:2 +4y=5 X eingesetzt |-6 = 2 = -1 = 5 = 2 = X 14 = {(61-4)} - 1 2x+4y = 12 1-2x-3y = -10

Öffnen

Page 2: Word Problem Application

This page applies linear equations to a real-world scenario involving the pricing of pencils and erasers.

Example: 14x + 3y = 6.90 and 2x + y = 3.10, where x represents the price of a pencil and y represents the price of an eraser.

Highlight: The solution demonstrates how to interpret word problems and translate them into mathematical equations.

The problem is solved systematically, first isolating one variable and then solving for the other. The final answer is presented clearly, stating that one pencil costs €1.20 and one eraser costs €0.70.

Page 1: Solving Systems of Linear Equations

This page demonstrates solutions to systems of linear equations with two variables. The problems involve finding the intersection points of lines represented by these equations.

Example: 3x + 4y = 16 and x = 2 are solved simultaneously to find the point of intersection (2, 2).

Highlight: The page showcases different methods of solving systems, including substitution and elimination.

Vocabulary: "Eingesetzt" means "substituted" in German, indicating the substitution method used in solving these equations.

The solutions are presented step-by-step, allowing students to follow the problem-solving process clearly. The page also includes graphical representations of the solutions, helping to visualize the intersection points.

Page 5: Continuation of Three-Variable Systems

This page continues the solution process for the three-variable system introduced on the previous page.

Example: The final solution set is presented as K = {(1, 2, 3)}, representing the values for x, y, and z respectively.

Highlight: The page demonstrates the importance of checking the solution by substituting the values back into the original equations.

The step-by-step process shown here is crucial for understanding how to solve complex systems of equations and verify the correctness of the solution.
