Solve each of the following in equations and represent the solution set on the number line.

< 2, x ϵ R.


Given:


< 2, x ϵ R.


-2 < < 2


> -2 and < 2


When,


> -2


Adding 2 to both sides in the above equation


+ 2 > -2 + 2


> 0


> 0


> 0


Signs of 4x – 3:


4x – 3 = 0


(Adding 3 to both sides and then dividing both sides by 4)


4x – 3 > 0


(Adding 3 to both sides and then dividing both sides by 4)


4x – 3 < 0


(Adding 3 to both sides and then dividing both sides by 4)


Signs of x – 1:


x – 1 = 0 x = 1 (Adding 1 to both the sides)


x – 1 > 0 x > 1 (Adding 1 to both the sides)


x – 1 < 0 x < 1 (Adding 1 to both the sides)


At x = 1, is not defined.


Intervals that satisfy the required condition: > 0


or x > 1


Now, when < 2


Subtracting 2 from both the sides


-2 < 2 -2


< 0


< 0


< 0


Signs of x – 1:


x – 1 = 0 x = 1 (Adding 1 on both the sides)


x – 1 < 0 x < 1 (Adding 1 on both the sides)


x – 1 > 0 x > 1 (Adding 1 on both the sides)


At x = 1, is not defined


Interval which satisfy the required condition: < 0


x < 1


Now, combining the intervals:


or x > 1 and x <1


Merging the overlapping intervals:



Therefore,



1
