Question

Solve |2x + 8| = 20.

Answer 1

{-14, 0}

{-14, 6}

{-6, 14}

{0, 14}
but these are the answers what am i doing wrong?

Answer 2

20-8=12

Answer 3

im confused

Answer 4

You need to subtract 8 from both sides

Answer 5

ok i got 2x=12

Answer 6

so, x=12/2 = ... ?

Answer 7

6

Answer 8

correct, fot the first case!

Answer 9

*for

Answer 10

then i plug in 6 for x?

Answer 11

Since the equation has an absolute value in it you need to set up 2 different equations.
One for each sign.

Answer 12

what chu mean ziggy?

Answer 13

(2x+8) = 20 and -(2x + 8) = 20

Answer 14

???

Answer 15

yeah, that's i mean
u just solved the first case : 2x+8=20, u got x=6
but not yet solve for -(2x+8)=20, find this solution!

Answer 16

I'm not sure how you factored out your x, the second step for that should be to add 8 to both sides of the equation.

Answer 17

dont use x=6 to this problem (it is was clear)
just solve for x

Answer 18

Yeah, there are two solutions for x. 6 is the first but you need to find the second of them.

Answer 19

i got -6 now?

Answer 20

still incorrect, try again

Answer 21

-(2x + 8) = 20
-2x - 8 = 20
+ 8 + 8
-2x = 28
