Question : 71 of 100

Marks: +1, -0

If 2x+ 4(x - 3) < -2 - x < 2x - 1, then find the value of x.

Solution:

Expression 1 :

-2-x<2x-1

⇒

2x+x>1-2

⇒

x>1/3

----(i)
Expression 2 :

2x+4(x-3)<-2-x

⇒

6x-12<-2-x

⇒

6x+x<12-2

⇒

x<10/7

----(ii)
Combining inequalities (i) and (ii), we get :

-1/3

x

10/7

Thus, only value that can take among the options = 1
