Question

What is the solution to the system of equations?

y = 1/3x - 10

2x + y = 4

(–8, 6)
(–6, 16)
(6, –8)
(16, –6)

Answer 1

this one seems like the first one we did already...

Answer 2

just try to do the same thing as the first problem we helped you with

Answer 3

Yes!

Answer 4

so would the answer be D?

Answer 5

y = A system of equations. y equals StartFraction one-third EndFraction minus 10. 2 x plus y equals 4.x – 10?
what is this supposed to be.

Answer 6

i don't really understand what the first equation is bc it is weirldly typed

Answer 7

but if you plug those numbers in and it works, than it is the right anwer.

Answer 8

could you please retype the first equation plz?

Answer 9

thanks

Answer 10

done

Answer 11

just tell us how you got ur work then we can check it

Answer 12

ummmm so i combined -10 and -4

Answer 13

actually ill see if what you got is right. hold up

Answer 14

??

Answer 15

are you sure you typed the equations correctley for the problem?

Answer 16

yes

Answer 17

you said ur answer was D the 4th one?

Answer 18

uhh??

Answer 19

ok well ill take you step by step.

Answer 20

okay thanks

Answer 21

1. since 2x+y=4 , the equation 1/3x-10 would be substituted into Y.
this would be 2x+1/3x-10=4

Answer 22

after this step, isolate the Xs to one side and the numbers without X to the other side.

Answer 23

we would end up with 2x+1/3x=10+4

Answer 24

it showed me a graph for some reason

Answer 25

oh. thats weird. but do you understand the steps so far?

Answer 26

2 1/3x -10 = 4

Answer 27

that would be 2x+1/3x-10=4, then we move the 10 to the other side and would end up with 2x+1/3x=14. do you understand?

Answer 28

ok

Answer 29

we combine like terms and get 2x+1/3x which would end up being 7/3x. 10+4=14.
7/3x=14. do you understand this?

Answer 30

kinda

Answer 31

ok what do you need help understanding?

Answer 32

do i still have to divide 7/3x to equal 14

Answer 33

Ill help you understand. So:
1. we start with y=1/3x-10 and 2x+y=4
2. Since 2x+y=4 has a Y inside the function, Y=1/3x-10 could be substituted in place of that Y

Answer 34

7/3x=14 . To solve this you do 14 divided by (7/3) and that is your answer for X

Answer 35

then to find Y, you would plug that X answer into all the X variables to find Y.

Answer 36

hopefully you understand. Does this help?

Answer 37

so B?

Answer 38

Does 14/(7/3) have a negative in it? No it doesn't so that means X can't be negative

Answer 39

c?

Answer 40

Yes! correct good job

Answer 41

finally...lol

Answer 42

do you need hlep understanding any of these concepts?

Answer 43

sorry i was in a zoom

Answer 44

math is my weakest subject

Answer 45

its alright.
