Answer 2

1]

x - 5 > 8

x > 8 + 5

x > 13

2] sampe 10] konsepnya sama, hanya pindah ruas, yg negatif (-) jadi positif (+)

11]

4a ≤ 3a + 7

4a - 3a ≤ 7

a ≤ 7

12]

5a - 4 > 4a + 4

5a - 4a > 4 + 4

a > 8

14]

2 < x + 4 < 9

2 - 4 < x + 4 - 4 < 9 - 4

-2 < x < 5

15]

-3 ≤ x - 7 ≤ 5

-3 + 7 ≤ x - 7 + 7 ≤ 5 + 7

4 ≤ x ≤ 12

16]

4 1/2 < x + 1/2 < 8

4 1/2 - 1/2 < x + 1/2 - 1/2 < 8 - 1/2

4 < x < 7 1/2

17]

1/2 (8p + 3) ≥ 3 + 2 1/2

1/2 (8p + 3) ≥ 11/2

Kalikan 2

8p + 3 ≥ 11

8p ≥ 11 - 3

p ≥ 8/8

p ≥ 1
