Giovani Abbott · Answer 1

6n = 30 + 3 (n - 4)

6n = 30 + 3n - 12

6n = 3n + 18

-3n

3n = 18

/3 / 3

n = 6

Larry Frank · Answer 2

6n = 30 + 3 (n - 4)

6n = 30 + 3n - 12 because you simplified the parenthesis

then subtract 12 form 30 to simplify equation

6n = 18 + 3n

then subtract 3n from both sides

6n - 3n = 18 + 3n - 3n

3n = 18

than simplify the equation: divide both sides by 3

n = 6
