Question

Please help me? (:

Solve x + 3y = 93x - 3y = -13


(1, 10/3)
(1, -10/3)
(-1, 3/10)
(1, -3/10)

Answer 1

where does the first equation end and the second one begin?

Answer 2

It's combined

Answer 3

Is it

x + 3y = 9
3x - 3y = -13

or is it

x + 3y = 93
x - 3y = -13

Answer 4

I believe the first one

Answer 5

WAIT, it's the second

Answer 6

x + 3y = 93x-3y

Answer 7

x + 3y = 93
x - 3y = -13
------------
2x+0y = 80


So 2x = 80

what is x?

Answer 8

( I know it's confusing, but that's how my professor has me do it)

Answer 9

I don't know, i suppose I should find out. I think it has you wanting to solve for x.

Answer 10

hmm it can't be the second one, none of the answer choices match

Answer 11

It may have me solving for both x and y

Answer 12

x + 3y = 9
3x - 3y = -13
--------------
4x + 0y = -4

so

4x = -4

what is x?

Answer 13

Try it the way I mentioned :)

Answer 14

What do you get when you solve 4x = -4 for x?

Answer 15

-16

Answer 16

But that's irrelevant

Answer 17

no, you don't multiply

Answer 18

4 times something = -4

what is that "something"?

Answer 19

I have no clue

Answer 20

well 4 times 1 = 4 right?

Answer 21

-1

Answer 22

so x = -1

Answer 23

:) oh

Answer 24

now use this to find y

Answer 25

Ok, hmmm

Answer 26

Point me in the right direction?

Answer 27

I don't know if it'd be 10 over 3 or the opposite

Answer 28

if x = -1, then

x + 3y = 9

-1 + 3y = 9

3y = 9+1

3y = 10

What's the last step?

Answer 29

to figure out why

Answer 30

To figure out what "Y' equals

Answer 31

exactly, how do we do that?

Answer 32

10+3 = 13

Answer 33

no

Answer 34

get y by itself

Answer 35

you need to undo the multiplication by doing what?

Answer 36

or divide

Answer 37

on both sides?

Answer 38

yes, divide both sides by 3

Answer 39

10/3 3.3333333

Answer 40

i'd keep it as a fraction, so y = 10/3

Answer 41

oh my god youre the best tutor

Answer 42

thanks lol

Answer 43

But one quick question, how can you decipher whether it'd be 10/3 or 3/10?

Answer 44

it's 10/3 because you go from

3y = 10

to

y = 10/3

when you divide both sides by 3

Answer 45

Oh, alright

Answer 46

You're really good at this I may add

Answer 47

Hahahaha, that was a math pun "add"

Answer 48

lol yes a very good one

Answer 49

thanks for the compliment

Answer 50

I really do appreciate your help, you've been the best on here

Answer 51

yw, I'm glad to be of help

Answer 52

I'm good at English, Psych, and Philosophy, but I don't have much to contribute when it comes to math

Answer 53

you'll get better at it, just keep practicing

Answer 54

I know everyone has their strong suites and their weaknesses, but being enrolled in math all over again makes me feel insecure about my skills, or lack of I should say.

Answer 55

start with what you know and build from there

Answer 56

you'll improve your skills if you can translate it to your own language

Answer 57

You have to have somewhere to start with in order to build, like the order of operations, hahaha all of these puns!

Answer 58

No, but you're right. I'm only joking, but i know where I can start and build up

Answer 59

My language will never be able to translate math

Answer 60

lol fun puns (love me some puns)

it will, just keep at it and you'll be able to translate

Answer 61

try to connect it to your strengths (like eng or psych)

Answer 62

Thank you for all of your help

Answer 63

you're welcome

Answer 64

There's a 100% chance i'll need more of your knowledge

Answer 65

the thing is, once i feel i know how to go on with other problems< i come across on that completely doubts my ability to achieve

Answer 66

lol alright

Answer 67

ooops no backwards shark thing

Answer 68
