Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

Answer:
School is better than virtual learning because you have better one on one connection. With virtual learning, you have to email your teacher and pray she emails you back in time. Though with brick and mortar school, you can walk right up to your teacher and ask for help as you are working. Also, normal school is better because you won't have to worry about internet connection and if your computer is 'compatible'. With virtual learning, you may have to wait a while as your computer loads, but in real school, you have immediate help to all your needs.
