Question

|x| = 4
|x| − 8 = −5
−3|2x + 6| = −12

Answer 1

Are there 3 separate questions?

Answer 2

For the first one x=4 or x=-4

Answer 3

yes marinda

Answer 4

Do you know how to solve absolute equations, do you need help?

Answer 5

ALOT of help... i kinda had a dumba** 4 a teacher

Answer 6

That's fine, i'm sure you're not dumb.

Solving inequalities isn't that hard. Instead of solving one equation you have to solve two. The positive answer and the negative one.

Let's look at |x| − 8 = −5
First step is to get the absolute part by itself, can you do that?

Answer 7

sorry i meant to write solving absolutes :)

Answer 8

i have no idea how to do that.

Answer 9

Answer 10

That okays so |x| − 8 = −5
We want to take the 8 over to get the absolute by itself, to do this add 8 to both sides

|x|-8+8=-5+8
|x|=3

Answer 11

so basically its just like solving a normal equation

Answer 12

exactly here's where it differs.
because an absolute always gives a positive value
x=3 or x=-3

Answer 13

so your always going to have two answers one positive and one negative?

Answer 14

yes but they are not necessarily the same number. let's try the last one it will help explain

−3|2x + 6| = −12
now make the absolute part on it's own. what do you get?

Answer 15

are you able to do that? it's just like solving for a normal equation

Answer 16

|2x+6|=4

So 2x+6=4 or 2x+6=-4

Solve like normal, hope it helps

Answer 17

i get it now.. thank you very much
