प्रश्न
Solve 3x + 8 > 2, when x is a real number.
उत्तर
The given inequality is 3x + 8 > 2.
3x + 8 > 2
⇒ 3x + 8 - 8 > 2 - 8
⇒ 3x > - 6
⇒ `(3x)/3 > (-6)/3`
⇒ x > - 2
When x is a real number, the solutions of the given inequality are all the real numbers, which are greater than –2.
Thus, in this case, the solution set is (– 2, ∞).
