Chapter 10 - 10.1 - Matrices and Systems of Equations - 10.1 Exercises - Page 709: 17


$$\begin{bmatrix} 1&-1&2&\vdots&2 \\4&-3&1&\vdots &-1 \\2&1&0&\vdots &0 \end{bmatrix}$$

Work Step by Step

In order to write a matrix that would solve this linear equation, we write the coefficients of each variable in their own column. Doing this, we find: $$\begin{bmatrix} 1&-1&2&\vdots&2 \\4&-3&1&\vdots &-1 \\2&1&0&\vdots &0 \end{bmatrix}$$
