Use the matrix method to solve the system of equations 2x + 4y = 8 and 6x + 3y = -3. the resulting matrix is: 1 0 -2 0 1 3 1 0 2 0 1 3 0 1 -2 1 0 3

The calculator function that puts the augmented matrix

into reduced row-echelon form will give you an identity matrix in the left columns and the solution in the rightmost column:

This corresponds to the first selection.

too hard the other guy did it

step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)
