Math Problem Statement
solve matrix
Solve the matrix system shown in the image.
Solution
The matrix in the image is:
1 & 1 & 1 & 4 \\ 1 & -1 & 2 & 3 \\ 2 & 3 & -1 & 6 \end{bmatrix}$$ This appears to be a system of equations written in augmented matrix form. To solve this, we can use methods such as **Gaussian elimination** or **Gauss-Jordan elimination**. I'll proceed with the Gaussian elimination to convert the matrix to row echelon form, and then back-substitute to find the solution. Let me perform the steps to solve this.The augmented matrix has been reduced to: $$\begin{bmatrix} 1 & 1 & 1 & 4 \\ 0 & 1 & -0.5 & 0.5 \\ 0 & 0 & 1 & 1 \end{bmatrix}$$ From this, we can back-substitute and find the solution to the system of equations: $$x_1 = 2, \quad x_2 = 1, \quad x_3 = 1$$ This means the solution to the system is: $$x_1 = 2, \quad x_2 = 1, \quad x_3 = 1$$ Would you like more details on the steps involved? Here are some related questions: 1. How does Gaussian elimination work? 2. What is the purpose of row reduction in solving a matrix? 3. Can this system be solved using other methods like Cramer's rule? 4. How does back substitution work in a system of equations? 5. What are the applications of solving systems of equations in real life? **Tip:** Gaussian elimination is a systematic method to solve systems of linear equations by transforming the system into upper triangular form.Ask a new question for Free
