Question

Write the augmented matrix for each system of equations. -2x-2y+5z=1. -5x-5y+7z=4

Answer 1

The augmented matrix is:

`\left[\begin{array}{cccc}-2&-2&5&1\\-5&-5&7&4\end{array}\right]`

Explanation:

This system of two equations with three unknowns will generate an augmented matrix that consists of two rows and four columns:

`\left[\begin{array}{cccc}-2&-2&5&1\\-5&-5&7&4\end{array}\right]`
