Math Problem Statement

Write the system of equations as an augmented matrix: 7x - y = 12 3x + y = 8 Write the system of equations that corresponds to the augmented matrix: [ 6 -4 -3 | -44 ] [-1 -5 2 | -18 ] [ 4 3 5 | 13 ]

Solution

For Question 4, you are asked to write the given system of equations as an augmented matrix. The system provided is:

7x - y &= 12 \\ 3x + y &= 8 \end{aligned}$$ ### Writing this as an augmented matrix: The coefficients of the variables and the constants from the right-hand side of the equations will be placed in the matrix: $$\begin{bmatrix} 7 & -1 & | & 12 \\ 3 & 1 & | & 8 \end{bmatrix}$$ This matrix represents the system of equations. The first column corresponds to $$x$$, the second column corresponds to $$y$$, and the last column after the vertical bar represents the constants on the right-hand side of the equations. --- For **Question 5**, you are asked to convert the given augmented matrix into a system of equations. The augmented matrix provided is: $$\begin{bmatrix} 6 & -4 & -3 & | & -44 \\ -1 & -5 & 2 & | & -18 \\ 4 & 3 & 5 & | & 13 \end{bmatrix}$$ Each row in this matrix represents a linear equation. The first three columns represent the coefficients of $$x$$, $$y$$, and $$z$$, respectively, and the last column represents the constants on the right-hand side. Thus, the corresponding system of equations is: 1. $$6x - 4y - 3z = -44$$ 2. $$-x - 5y + 2z = -18$$ 3. $$4x + 3y + 5z = 13$$ --- Would you like further details or clarifications? Let me know if you need any help filling in the blanks. Here are five additional related questions: 1. How do you solve an augmented matrix using Gaussian elimination? 2. What are the conditions for a system of equations to have a unique solution, no solution, or infinitely many solutions? 3. How can matrix row operations simplify solving a system of equations? 4. What is the significance of the determinant when solving systems of linear equations? 5. How can we determine if a matrix is invertible, and what role does it play in solving equations? **Tip:** When solving systems of equations with matrices, try to identify patterns in the coefficients to speed up the process of creating the augmented matrix.
