Ini gimana caranya kk?

Jawaban:

jawab no 2 dan 3

Penjelasan dengan langkah-langkah:

no 2

a). 2x = 18

x = 18÷ 2

x = 9

b). 3x + 4 = 25

3x = 25 – 4

3x = 21

x = 21 ÷ 3

x = 7

c). 5x – 2 = 18

5x = 18 + 2

5x = 20

x = 20 ÷ 5

x = 4

d). 4x – 3 = 2x + 17

4x -2x = 17 + 3

2x = 20

x = 10

no 3.

b). 3x + 10 ≤ 4

3x ≤ 4 – 10

3x ≤ -6

x ≤ -2

c). 4x – 2> 10

4x > 10 + 2

4x > 12

x > 3

d). 2x – 5 ≥ x + 6

2x – x ≥ 6 + 5

x ≥ 11
