-4 < 2x + 3 - 2 < 4
-4 < 2x + 1 < 4
-4 - 1 < 2x + 1 - 1 < 4 - 1
-5 < 2x < 3
-5 ÷ 2 < 2x ÷ 2 < 3 ÷ 2
[tex]\bold{ -\frac{5}{2}\ \textless \ x\ \textless \ \frac{3}{2}} [/tex]
atau
-2,5 < x < 1,5

|2x + 3| - 2 < 4
|2x + 3| < 6
(2x + 3)^2 < 6^2
4x^2 + 12x + 9 < 36
4x^2 + 12x - 27 < 0
(2x + 9)(2x - 3) < 0
x = -9/2 atau x = 3/2
