Answer 1

@J-bird

Answer 2

im here

Answer 3

k, igreen isn't

Answer 4

good

Answer 5

I have a couple questions

Answer 6

its 3,negative 2

Answer 7

Which of the following is the solution of the given system of equations?

-negativex + y − z = 14

2y + z = negative-12

y = 2











(4, 2, 16)










(4, 2, negative-16)










(14, 2, negative-16)










(negative-4, 2, 21)

Answer 8

what grade are you in BTW

Answer 9

11th, it's pathetic I don't know algebra

Answer 10

i did algebra last year and im in 9th

Answer 11

you're smart, what's the answer



Which of the following is the solution of the given system of equations?

-negativex + y − z = 14

2y + z = negative-12

y = 2











(4, 2, 16)










(4, 2, negative-16)










(14, 2, negative-16)










(negative-4, 2, 21)

Answer 12

why are there 3 digits for answers?? i only see z and y

Answer 13

oh nvm i see it

Answer 14

cause there's a -x

Answer 15

ok so z=8 y=2 with those number can you figure out x??

Answer 16

and stuff

Answer 17

get out of here reaves im trying to help him

Answer 18

hmm hang on a sec

Answer 19

not really, I don't really have time , I have like 4 more Q's and only 7 mins

Answer 20

z= -16

Answer 21

Solve by back substitution.

x + 2y + z = 4

x + z = 4

z = 2











(3, 1, negative-2)










(2, 0, 2)










(negative-1, 0, negative-2)










(2, 1, 2)

Answer 22

z and x both equal 2

Answer 23

let me find y a sec

Answer 24

its 2 0 2

Answer 25

Solve by back substitution.

y = negative-2

x + y = negative-4

x + y + 5 = z











(0, negative-2, 0)










(negative-2, negative-2, 1)










(2, negative-2, 0)










(1, negative-2, 1)

Answer 26

-2 -2 0

Answer 27

CAN YOU SHOW WORK FOR THIS

Solve the system by substitution.
negative-3 x − 3 y = 3
y = negative-5 x − 17

Answer 28

one sec

Answer 29

sorry taking so long this one is harder XD

Answer 30

-3x and -3y. to pass off showing your work, just substitute them into the equation, thats what i did and aced algebra

Answer 31

If you get the solution 12 = 5 there is no solution to the system of equations.











True










False

Answer 32

@J-bird

Answer 33

true

Answer 34

last one







If you get the solution 1 = 9, there are infinitely many solution to the system of equations.











True










False

Answer 35

false

Answer 36

0=0 is infinitely many solutions

Answer 37

thanks
