Tentukan himpunan penyelesaian dari

Jawaban:

A. 5x-10= 15

→ 5x = 15 + 10

→ 5x = 25

→ x = 5

B. 2a+4 =2

→ 2a = 2 – 4

→ 2a = (-2)

→ a = (–1)

C. 6a-3= 6

→ 6a = 6 + 3

→ 6a = 9

→ a = 9/6

→ a = 3/2

→ a = 1,5

D. 4x-4 = 8

→ 4x = 8 + 4

→ 4x = 12

→ x = 3

E. 7a+7 = 28

→ 7a = 28 – 7

→ 7a = 21

→ a = 3
