Tolong bantu jawab ya teman-teman ^^ Dengan cara yang lebih detail

1)
a. -5 ≤ 2x + 6 < 4
-5 -6 ≤ 2x +6 -6 < 4 – 6
-11 ≤ 2x ≤ -2
-11/2 ≤ x ≤ -1

b. (2x + 8)/5 > 6
2x + 8 > 6(5)
2x > 30-8
2x > 22
x > 11

c. 2x/3 + 2 < 1
2x/3 < 1 – 2
2x < -1/3
x < -1/6

2)
a. x² + 5x + 4 > 0
(x + 1)(x + 4) > 0
x + 1 > 0
→ x > -1

x+4 > 0
→ x > -4

b. x -1/x+2 > 2
(x-1)/(x+2) – 2(x+2)/(x+2) > 0
( x – 1 – 2x – 4)/(x+2) > 0
( – x – 5)/(x + 2) > 0
-x – 5 > 0
-x > 5
→ x < -5

x + 2 > 0
→ x > -2
