Question

can some check my answers plz?

Answer 1

sure i can try

Answer 2

What is the value of a in the equation a = 2 + 3a + 8?
10
5
−5
−10
I believe it is 5

Answer 3

What is the solution to the equation 3x + 2(x − 9) = 8x + x − 14?
−8
−1
1
8
Answer that i think fits: -1

Answer 4

am i solving for = a or 3a

Answer 5

A

Answer 6

ok fist you will have to get both as by it self

Answer 7

what i did first was subtract 3a from both 3 and 8

Answer 8

2 and 8*

Answer 9

you want A by it self so you will have to move 3a over to A

Answer 10

but fist to make we will work right to left so what is 8+2

Answer 11

@Ray_Masters

Answer 12

a = -5

Answer 13

Let's solve your equation step-by-step.
a=2+3a+8
Step 1: Simplify both sides of the equation.
a=2+3a+8
Simplify: (Show steps)
a=3a+10
Step 2: Subtract 3a from both sides.
a−3a=3a+10−3a
−2a=10
Step 3: Divide both sides by -2.
−2a
−2
=
10
−2
a=−5

Answer 14

please don't give direct answers

Answer 15

i want to understand it

Answer 16

btw 8+2 is 10

Answer 17

ok so first add 5+2 you can only add these numbers together because they don't have A and are on the right side and can be added together

does that make scene

Answer 18

yes so far

Answer 19

what do you have now that you done that

Answer 20

i have now is this
a=2+3a+8+2
8+2
10/2 =5
then 5+2 = 7
(thanks for the help i'm not that good in math)

Answer 21

no

Answer 22

that is not right

Answer 23

ok my bad then

Answer 24

ok let me help walk you though it

Answer 25

so you had a = 2 + 3a + 8?

all you did was add the real numbers together

so you added 2+8 which is 10
so now you got
A=3a+10

make sure you know if the number you are adding or subtracting is a positive or a negative in this case scene the + sign is in front of the 8 it make it a positive but if it where - 8 8 would be a negative

you don't need to worry about that now the point is make sure you check the sign

ok now can you add 10 + 3A

Answer 26

The answer I gave is right, because I just did it on my quiz! Also if you need help, use this http://www.mathpapa.com/algebra-calculator.html

Answer 27

@Ray_Masters do you get what I'm saying

Answer 28

yes a little bit it's still a little fuzzy but i think i get it

Answer 29

ok so you have a=3a+10

can you add 3a +10

Answer 30

if i add that wouldn't that be like 13a or something (do i even add the a?) :/

Answer 31

The first step is combining like terms, so a=2+3a+8 would be: a =3a + 10
Next you need to isolate the variable, so subtract 3a from a. (any lone varible equals 1) so you would have: -2a = 10
Then you would divide both sides of the equation by -2.
The answer is a = -5

Answer 32

Good luck with your quiz. :)

Answer 33

no you don't add the a you never add a number with a letter

and you never add a letter with a letter but itself

example

you cant add 1 + a1

but you can add 1+1

you also cant add A1 +b1

but you can add A1+a1

makes scence

Answer 34

ohhhh got it,

Answer 35

ok so you have a=3a+10

we need to get a by it self so what do we do

we need to bring 3a over to a but how do we do that

Answer 36

sorry this is taking forever) and we subtract 3a from 10?

Answer 37

ok i will try to make this fast

Answer 38

bring 3a over to a

a−3a=3a+10−3a

Answer 39

sorry had to do something

Answer 40

a is like saying 1

Answer 41

so basically its 1-3

Answer 42

ok so A is 1 and you subtract that from 3

Answer 43

yes

Answer 44

when there is no number with a letter it is one I know it might be confusing but that what I always leaned

Answer 45

so you would get
−2a=10 you still keep the a

3a the a is not 1 because it has 3 as in a you only have 1 a so instead of saying 1a you just say a

Answer 46

ok makes sense

Answer 47

ok but you still need a by itself

Answer 48

so how would we do that

Answer 49

ok to make it go fast because i know you already spent a lot of time trying to it out i will give it to you divide both side by -2


−2a/2=10/2

Answer 50

i was having a little war with myself over if we times or / lol

Answer 51

i mean -2 and lol

Answer 52

so you / -2 from 10 and that's how you'll get ur answer?

Answer 53

yes you should get a=−5

Answer 54

you have to do it to both sides

Answer 55

ok cool, thanks for your help with this even if it took forever for me to get it,

Answer 56

btw you have to do 10 /-2 not -2/10

Answer 57

ok

Answer 58

np you will not believe how long it took my to do these hope you have a great day :)

Answer 59

you to as well lol thnxs for taking the time out to help me
