Solve the system of equations by transforming a matrix representing the system of equation into reduced row echelon form. 2x+y−3z=−19x+2y+z=−4x−y+5z=21

What is the solution to the system of equations?

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

i believe that the answer is

b. y-1=-2(x-4)

hope this !

i have no clue what you just said. write a question in english?
