Math Problem Statement

En los problemas 9 a 20 escriba el sistema de ecuaciones representado por la matriz aumentada correspondiente.

Solution

To solve this, we’ll translate each augmented matrix into a corresponding system of linear equations. I’ll start by converting the first few matrices to systems of equations and explain the process. Let me know if you'd like me to continue with the rest or need clarification on any particular matrix.

Problem 9

Given matrix:

-3 & -2 & -1 & | & 1 \\ 2 & 5 & 1 & | & 3 \\ \end{pmatrix}$$ Assuming variables $$x$$, $$y$$, and $$z$$ (left to right): 1. $$-3x - 2y - z = 1$$ 2. $$2x + 5y + z = 3$$ ### Problem 10 Given matrix: $$\begin{pmatrix} 1 & 1 & -1 & | & 7 \\ 4 & -1 & 5 & | & 4 \\ 6 & 1 & 3 & | & 20 \\ \end{pmatrix}$$ System of equations: 1. $$x + y - z = 7$$ 2. $$4x - y + 5z = 4$$ 3. $$6x + y + 3z = 20$$ ### Problem 11 Given matrix: $$\begin{pmatrix} 0 & 1 & 2 & | & 0 \\ 1 & 0 & 3 & | & 5 \\ 0 & 0 & 1 & | & 3 \\ \end{pmatrix}$$ System of equations: 1. $$y + 2z = 0$$ 2. $$x + 3z = 5$$ 3. $$z = 3$$ ### Problem 12 Given matrix: $$\begin{pmatrix} 2 & 3 & 1 & 4 & | & 7 \\ 4 & -6 & -3 & 11 & | & 10 \\ 0 & -2 & 0 & 1 & | & 0 \\ \end{pmatrix}$$ Assuming variables $$w$$, $$x$$, $$y$$, and $$z$$: 1. $$2w + 3x + y + 4z = 7$$ 2. $$4w - 6x - 3y + 11z = 10$$ 3. $$-2x + z = 0$$ ### Problem 13 Given matrix: $$\begin{pmatrix} 2 & 3 & 1 & 2 & | & 0 \\ 1 & 0 & 0 & 0 & | & 0 \\ 0 & 0 & 1 & 0 & | & 0 \\ \end{pmatrix}$$ Assuming variables $$w$$, $$x$$, $$y$$, and $$z$$: 1. $$2w + 3x + y + 2z = 0$$ 2. $$w = 0$$ 3. $$y = 0$$ Would you like me to proceed with the remaining matrices? --- Here are 5 related questions for practice: 1. How would you solve a system of linear equations using substitution? 2. What is the significance of an augmented matrix in linear algebra? 3. How can you determine if a system of equations has a unique solution, infinitely many solutions, or no solution? 4. What are the elementary row operations that can be applied to matrices? 5. How do you write a matrix in row echelon form? **Tip:** When converting matrices to equations, make sure to align each column with the correct variable.
