Answer 3

|5x – 4| < 21

21 + 4 / 5 = the answer.

Answer 4

|5x - 4| < 21

This breaks into two inequalities:

5x - 4 < 21

and

-5x + 4 < 21

------------

5x - 4 < 21

Add 4 to both sides:

5x < 25

Divide 5 to both sides:

x < 5

------------

-5x + 4 < 21

Subtract 4 to both sides:

-5x < 17

Can you divide 17 / -5? @pigglet
