divide the first equation by 3
i did x+2y-6z-36
check once more, make sure to divide everything by 3
so far everything seems right
okay what did you get
12z/3 = ?
(x+2y-4z = 12) now divide the third equation by 4
thats what you should get
not quite, try once more the third equation is 4x+8y-16z = 48 now divide this equation by 4
8y/4 = ?
yeah then you should get your answer
not quite.... 16z/4 = ?
ok i am getting confused its ok i can guess on this question
4x+8y-16z = 48 divided by 4 is x + 2y - 4z = 12, does that make sense?
i know the answer
4x/4 = x 8y/4 = 2y 16z/4 = 4z so the third equation becomes x + 2y - 4z = 12
is 12 a answerchoice
no the answers are above with my question; its an image with the choices to select from
what do you think it is
honestly i don't know i am going to try graphing it
kk try to graph it
are you getting it
not yet I'm just going to skip it
then come back
are you taking this test also? e2020
i did last summer because i do vitual
ok so your not takeing alg 2 this year
nope alredy did
