Answer 1

you want to isolate the absolute values
so first add 16 to both sides
then divide both sides by 3
then separate the absolute value into two equations

Answer 3

just follow the instructions jiggly gave you.

3|9+x| - 16 = 20
+16 + 16
3|9+x| = 36

9 + x = 12

9 + x = - 12

are your two equations just solve for x.
