Question
Solve the matrix Ax= b for x
Given \( A = \begin{bmatrix} 1 & -3 & 1 \\ 0 & 1 & -2 \\ 0 & 1 & -1 \end{bmatrix} \), \, \( x = \) and \( b = \begin{bmatrix} 300 \\ 150 \\ 400 \end{bmatrix} \).
Transcribed Image Text:Given \( A = \begin{bmatrix} 1 & -3 & 1 \\ 0 & 1 & -2 \\ 0 & 1 & -1 \end{bmatrix} \), \, \( x = \) and \( b = \begin{bmatrix} 300 \\ 150 \\ 400 \end{bmatrix} \).
The image contains a mathematical notation. It shows a column vector labeled as \( x \) on the left side. The vector has three rectangular placeholders within large brackets, suggesting that values or variables will be placed inside these placeholders to form a column vector. Each placeholder represents an element of the vector, but they are currently empty. This format is often used in linear algebra to denote vectors with unspecified components.
