Solution
To convert the given system of linear equations to a matrix equation of the form , we need to identify the coefficients of the variables and the constants on the right-hand side.
The system of equations is:
3x + 2y - z &= 200 \\ 2x + y + 4z &= 375 \\ 5x + 3y - 2z &= 225 \end{align*}$$ This can be rewritten in matrix form as follows: 1. **Matrix $$A$$** (the coefficient matrix): $$A = \begin{pmatrix} 3 & 2 & -1 \\ 2 & 1 & 4 \\ 5 & 3 & -2 \end{pmatrix}$$ 2. **Matrix $$X$$** (the variable matrix): $$X = \begin{pmatrix} x \\ y \\ z \end{pmatrix}$$ 3. **Matrix $$C$$** (the constant matrix): $$C = \begin{pmatrix} 200 \\ 375 \\ 225 \end{pmatrix}$$ Putting it all together, the matrix equation is: \[ [A][X] = [C] \] $$\begin{pmatrix} 3 & 2 & -1 \\ 2 & 1 & 4 \\ 5 & 3 & -2 \end{pmatrix} \begin{pmatrix} x \\ y \\ z \end{pmatrix} = \begin{pmatrix} 200 \\ 375 \\ 225 \end{pmatrix}$$ Would you like further details on solving the matrix equation or have any questions? Here are 5 numbered questions you can ask: 1. How do you solve a system of linear equations using matrix methods? 2. What are the properties of matrices that are useful for solving linear systems? 3. Can you explain the concept of matrix inversion and its application? 4. How can Gaussian elimination be used to solve this system? 5. What is the determinant of a matrix and how is it used in solving linear equations? **Tip:** When converting a system of equations to matrix form, ensure that the coefficients are correctly placed in the matrix to maintain the relationships of the equations.Ask a new question for Free
