Solve each of the following system of equations in R.

We know that, if we take reciprocal of any inequality we need to change the inequality as well.

Also,

|x|–3≠0

⇒ |x|>3 or |x|<3

For |x|<3

⇒ –3<x<3

⇒ x ϵ (–3, 3) …(1)

∴, The equation can be re–written as–

Adding 2 both the sides, we get–

|x|–3+3≥ 2+3

⇒ |x|≥5

We know that,

|x |≥a ⟺ x≤–a or x≥a

Here, a=5

⇒ x≤–5 or x≥5

⇒ x ϵ(–∞,–5 ] or x ϵ[5, ∞) …(2)

**⇒** **x** **ϵ****(–∞,–5 ]** **⋃** **(–3, 3)** **⋃** **[5, ∞)** **(from 1 and 2)**

We can verify the answers using graph as well.
