6. 3 matrices and systems of equations notes: sterling. Provide a generalization to each of the key terms listed in this section. A matrix is a rectangular array of numbers, which can be explain by the following array: Column 1 column 2 column 3 column j column n.

An augmented matrix is when you have a system of linear equations written as a matrix by writing. [only] the coe cients and even the constants that appeared in the original equations. Write the augmented matrix of the following system of equations. x + y = 8. 2x + 3y = 20 (cid:26)2x + 3y = 20 (cid:12)(cid:12)(cid:12)(cid:12) x + y = 8 (cid:12)(cid:12)(cid:12)(cid:12) (cid:20) 2x +3y. Write the augmented matrix of the following system of equations.
