Question

Represent the following system of linear equations as a single matrix equation of the form A = b,

where A is a 3 × 3 matrix, and x and b are 3 × 1 column matrices.
x+ 3y + 2z = 8
x− y + z = −2
2x+ 3y + 3z = 7

Answer 1

Answer:
`\left[\begin{array}{ccc}1&3&2\\1&-1&1\\2&3&3\end{array}\right] =\left[\begin{array}{c}8\\-2\\7\end{array}\right]`

Explanation:

each column of the matrix represent a variable, the first column represents the x, the second y, third z and b is the answer as a vector.
