Tentukan nilai x yang memenuhi persamaan berikut.↪5(2x – 6) = 30↪5x – 6 = 19​

5 ( 2x – 6 ) = 30

10x – 30 = 30

10x = 30 + 30

10x = 60

x = 60 / 10

x = 6

5x – 6 = 19

5x = 19 + 6

5x = 25

x = 25 / 5

x = 5

5(2x – 6 ) = 30

2x – 6 = 30/5

2x – 6 = 6

2x – 6 + 6 = 6 + 6

2x = 12

x = 12/2

x = 6

5x – 6 = 19

5x – 6 + 6 = 19 + 6

5x = 19 + 6

5x = 25

x = 25/5

x = 5
