Question

Solve for x: −5|x + 1| = 10
Answers
x = 0

x = −3 and x = 1

x = −1 and x = 3

No solution

Answer 1

do u know what || means?

Answer 2

im sry if i was rude :/

Answer 3

Do you want help figuring out how to do it, or just the answer?

Answer 4

@GotToLoveJenny there's a solution!

Answer 11

actually solutions :)

Answer 12

@Espree14 , give me ur reasoning on this question, what u got till now?

Answer 13

x = −3 and x = 1

Answer 14

Oh if it the one above than yes their is can somebody show me how to get it

Answer 15

But there isnt if there is a solution prove it please

Answer 16

|| is called modulus anything in between those two Pipes( | ) will become positive for example
| -2 | = 2
| 2 | = 2
so by this if we have an equation |x| = 2 then x maybe 2 or -2

Answer 17

yes okay....keep going

Answer 18

so for modulus problems we always have to take two cases
* one positive
* one negative
so here −5|x + 1| = 10
lets just simplify before we split our modulus, ie −|x + 1| = 2 => |x + 1| = -2 right?

Answer 19

Yes I think so

Answer 20

im going to check my work

Answer 21

now here we need to take two cases (x+1) which is positive and -(x+1) which is negative as
|x+1| = | -(x+1) |
so now
x+1 = -2 => x = -3
-(x+1) = -2 => x+1 = 2 => x = 1

Answer 22

i still got no solution

Answer 23

Nevermind, none of these options could leave you with a positive 10..
my bad, you where right @GotToLoveJenny!

Answer 24

yayyyyyyyyyyyyyyyyyyyyyyyyy

Answer 25
