Question

Solve the system of equations(use either substitution or elimination). SHOW ALL WORK


3x-2y=10
2y=6x-4

Answer 1

I just did a bunch of these.

Answer 2

I am doing it for extra credit

Answer 3

ok ill medal you f u help me out

Answer 4

Give me a minute and I might be able to give answer. I am working it out on paper.

Answer 5

ok

Answer 6

also I need the step by step process because it says to show all work

Answer 7

Okay

Answer 8

Okay so let me type all this out.

Answer 9

\[3x-2y=10\]\[2y=6x-4\]

Answer 10

So to find the answer, I am using the substitution method. It is easier for me.

Answer 11

So to start off, you need to move your variables. So, (give me a sec)

Answer 12

\[3x-2y=10\] and \[6x-2y=-4\]

Answer 13

What do you think we do next?

Answer 14

Idk thts why I am asking you for help

Answer 15

Okay. I was asking because you need to know this. If you keep asking in here istead of knowing, you won't be prepared for eos exams. Give me a minute and I will type out the next step.

Answer 24

2y=6x-4 divide both sides by 2 to solve for y
what would you get?

Answer 25

wait would I divide on the 6 or the 4

Answer 26

both :)

Answer 27

so I would divide by 2 on all 3 of them

Answer 28

yes :)

Answer 29

I got y=3x-2

Answer 30

that's right :)
then plug in 3x - 2 for y
into 3x-2y=10

so you get 3x - 2(3x-2) = 10 can you solve for x from there? :)

Answer 31

would I multiply 3x-2 times 3x-2

Answer 32

distribute the negative 2 into (3x-2)
so 3x - 2(3x-2) = 10 becomes
3x - 6x + 4 = 10 now add like terms

Answer 33

I got 9x from adding 3x+6x

Answer 34

3x - 6x

what is 3 minus 6?

Answer 35

3-6 is negative 3

Answer 36

yes :)
so -3x + 4 = 10 now subtract 4 from both sides :)

Answer 37

-3x=6

Answer 38

good!
now divide both sides by negative 3

Answer 39

I would get x=-3

Answer 40

6 divided by (-3) = ?

Answer 41

-2

Answer 42

yes!
so x = -2 :)
do you understand that?

Answer 43

its somewhat comin to me

Answer 44

ok
then to get y
plug in x = -2 into the equation y = 3x - 2
so y = 3(-2) - 2 = ?
