Question

2|x+2|-1=5

Answer 1

2(x+2)-1=5
2x+4-1=5
2x+3=5
2x/2= 2/2
x=1

Answer 2

add 1, first get
\[2|x+2|=6\] then divide by 2 and get \[|x+2|=3\]

Answer 3

one answer you have, namely \(x=1\) but you also have to solve
\[x+2=-3\] to get the second answer

Answer 4

yeah, that's what i'm having trouble with. i solved it, but i'm not getting the right answer according to the choices

Answer 5

i did it the way you showed above and this time i got x=-3 but that's still not right... i don't know what i'm doing wrong

Answer 6

a. x=4 or x=-8
b. x=1 or x=-1
c. x=1 or x=-5
d. x=5 or x=-5

i'm getting nowhere near that???

Answer 7

@e.cociuba can you help?

Answer 8

So when you tried to solve x+2=-3
what did you get exactly?

Answer 9

keep in mind that \(\bf |x+2|=3\implies
\begin{cases}
+(x+2)=3\\ \quad \\
\bf -(x+2)=3
\end{cases}\)

so you'd get 2 values for "x", 1 for each scenario

Answer 10

Oh, @myininaya so
2|x+2|-1=-5
divide everything by 2
x+2-1=-5
x+2=-6
x=-8

Answer 11

i didn't do that right omg i'm so confused

Answer 12

-5+1 is not -6

Answer 13

taylor try wolframalpha.com
it can probably help you alot with math

Answer 14

I think @jdoe0001 gave you a good explanation!

Answer 15

but yeah still a little wrong
I was just asking you to solve the one equation I gave you since you already found the other solution.

Answer 16

x+2=-3

Answer 17

Do you know how to get to x+2-1=-5
why and how?

Answer 18

You already solved x+2=3

Answer 19

Whatever, you guys do this!

Answer 20

Please don't just give the answer.

Answer 21

She can do this.

Answer 22

2|x+2|-1=5

Isolate the | | part.
That means solve for |x+2| like this:

Add 1 on both sides.

2|x+2|=6

Divide both sides by 2.

|x+2|=3


This means you have x+2=3 or x+2=-3

Answer 23

How I'm asking you do is to solve x+2=3 which you already did and got x=1.

Now you solve x+2=-3 to get the other solution.

seriously, if you dont plan on being a mathematician or any thing its ok to use a calculator or a program to help you

Answer 25

Yeah wolfram is great once you get a handle on simple algebra.

Answer 26

i suppose your right, but you can also brake down the problem and it will show you step by step how it got the answer.

Answer 27

ohhhhh!! so x= -5
x= -5 or x= 1
@myininaya

Answer 28

yes ^

Answer 29

Yes. Because you subtract 2 on both sides. x+2=-3
x=-3-2=-5
Great.

Answer 30

@Futuristicmario thank you so much, i will definitely check it out
@myininaya thank you oh my gosh you saved me
