1. 6|6-4x| = 4+8 = 12.

Divide both sides by 6 to isolate bracket:

|6-4x| = 2

6-4x = +-2

-4x = +-2 - 6

-4x = 2-6 = -4

X = 1.

-4x = -2-6 = -8

X = 2.

Solution set: X = 1, and X = 2.

2. 5|x+3|4 < 2.

20|x+3| < 2

|x+3| < 2/20

|x+3| < 1/10

x+3 < 1/10

X < 1/10 - 30/10

X < -29/10.

-x-3 < 1/10

-x < 1/10 + 30/10

-x < 31/10

X > -31/10.

Solution set: < -29/10, and X > -31/10.
