Solve the linear inequality

Question

X/2 L X/10 + 4

 

Interval Notation solution and Set-Builder notation solution

Answer 1

What Parviz wrote, and {x ∈ R | x < 10} is Set-Builder notation, where R is the set of all real numbers.

Answer 2

 X/2 < X/10 +4

 

X/ 2 - X/10 < 4

 

5X /10 - X/10 < 4

 

4X/10 < 4

 

  Divide both sides by 4

 

  X/ 10 < 1

 

   X < 10

 

  X ε ( -∝, 10 )
