Tentukanlah Penyelesaian dari:

Jawaban:

a.) x = 6

b.) a = 2

c.) x = 3,5

Penjelasan dengan langkah-langkah:

a.) 2x + 4 = 16

→ 2x = 16 – 4

→ 2x = 12

→ x = 12/2

→ x = 6

<============>

b.) 6a – 9 = 3a – 3

→ 3a – 9 = -3

→ 3a = -3 + 9

→ 3a = 6

→ a = 6/3

→ a = 2

<============>

c.) 3( 2x – 2 ) = 2x + 8

→ 6x – 6 = 2x + 8

→ 6x = 2x + 8 + 6

→ 6x = 2x + 14

→ 4x = 14

→ x = 14/4

→ x = 3,5

Jawaban:

a. 2x + 4 = 16

2x = 16 – 4

2x = 12

x = 12/2

x = 6

b.6a – 9 = 3a – 3

6a – 3a = -3 + 9

3a = 6

a = 6/3

a = 2

c. 6x – 6 = 2x + 8

6x – 2x = 8 + 6

4x = 14

x = 14/4
