ok so the answer should be 

-1 < x < - 5 ?

[Sw8 & Sal8y]

no this -1<x>-5

[Sw8 & Sal8y]

ok tell me how can u change the ineuality sign with -5?

it mean apne ye kaise kiya x<-5

[Sw8 & Sal8y]

dekhiye ap ne jo kaha k 2<x+3>-2 mujhe theek nhi lag raha ap lesson 2 ki example check kro table 1.2.2(b) k baad ki

 wo example hai

|x-3|<4

-4<x+3<4

-1<x<7

[Ahmed Ali Ghamidi]

Ji mene to isi method se kia he..

apka ek sign < or dosra > he, jub k mere khiyal me dono < or < hone chahye...

[Sw8 & Sal8y]

ap chahein toh lesson 2 mein check kr skte hain examples se n jonsi website maine batai thi wahan b signs change tabi hote hain jb multiply ya divide ho raha ho but yahan nhi ho raha

2<x+3>-2

stractract whole by -3

-1<x>-5

ye 1 example hai lesson to mein jo maine neeche di hai

|x+4|>=2

it is done by the alternate way

x+4<=-2                                        x+4>=2

x<=-6                                             x>=-2

now according to ur method

-2>=x+4>=2

subtract whole by -4

-6>=x>=-2

jb hum expand krte hain tab inequality ka sign change hota hai positive k  sath wohi sign rehta hai negative k sath change hota hai when u expand

 

[Ahmed Ali Ghamidi]

lakin is link pe http://www.purplemath.com/modules/absineq.htm

jo method bataya he us me to aisa nai hota, sign change nai hota in any case.

[Amara Shahid]

agar app dekhna chahte hain ke sign change hota he ya nahi to uski example

handouts mein hi hae page no.21
