2|3n-7| -8 = 12

2|3n-7| = 20

|3n-7| =10

Then -10 = 3n-7 = 10

-3 =3n =17

-1 = n = 17/3

Work it out.

2|3n – 7| - 8 = 12

2|3n – 7| = 20

|3n – 7| = 10

So, false.

2 I 3n - 7 I = 20

I 3n - 7 I = 10

So answer to question is FALSE

add 8 to both sides

so 2|3n – 7| = 20

divide both sides by two

|3n – 7|=10

false
