Answer 1

You must have mistyped the first one. It isn't an equation.
If you mean |x|+5=18, then you solve for x, like normal, then find the positive answer and the negative answer.
For one like 2, you'd have to set y+4<1 or y+4<-1

Answer 2

Yes I missed typed that I meant to put an = sign

Answer 3

I think number 1 is 13 or -13

Answer 4

Yes.

Answer 5

Ok I still don't get the other 3

Answer 6

Number 3 and 4 are the same as number 1 and I put up there ^^ what you need to do for number 2.

Because an absolute value can have either negative or positive answers, you have to set your equations/inequalities to reflect that.

Answer 7

Ok I see

Answer 8

I keep getting stuck after I subtract from one side and the other I don't know what to do after

Answer 9

Show me what you have.

Answer 10

I don't know much of what to do I left school early so I dident get to go through lesson in class

Answer 11

Like number one its just 18 -5 and you get 13 but it could be 13 or -13 that's how o got that answer

Answer 12

I*

Answer 13

Ok so number 2 you subtract 4 from both sides right?

Answer 14

Sorry subtract 4

Answer 15

thin you get - 3

Answer 16

that's where im stuck I don't know how to get the second number

Answer 17

OK, on #2
|y+4| < 1

Try it this way...either
-(y+4)>1

or (y+4)>1

Because what's in the sticks can either be positive or negative, right?

So, distribute the negative sign and you get
-y-4>1
Add 4 to both sides
-y-4>1

Answer 18

Sorry...
-y-4(+4)>1+4
-y>5
Now you need to multiply both sides by -1 to get y positive. When you multiply an inequality by a negative, you have to flip the sign around.
y<5
