Well first add 5 to both sides
4x-3=9
then add 3 to both sides
4x=12
then divide 4 by both sides.

|4x-3|-5=4
-------------------------------------------------
Step 1: Add 5 to both sides
-------------------------------------------------
|4x-3|-5+5=4+5
|4x-3|=9
-------------------------------------------------
Step 2: Solve absolute value
-------------------------------------------------
|4x-3|=9
-------------------------------------------------
we know either 
4x-3=9 or 4x-3=-9
-------------------------------------------------
possibility 1:
4x-3=9
4x-3+3=9 (Add 3 to both sides)
4x=12
4x/4 = 12/4 ( divide both sides by 4)
X=3
--------------------------------------------------------
possibility 2:
4x-3=-9
4x-3+3=-9+3 (Add 3 to both sides) 
4x=-6
4x/4 = -6/4 (divide both sides by 4) 
X=-3/2 
-----------------------------------------------------------
ANSWERS: x=3 or X=-3/2

Please Help! (10 POINTS)
Sliva [168]
The initial measure is:
 m1 = 28 ft
 The real measure must be:
 m2 = 14 ft
 The correct procedure to determine the scale factor is:
 k = m1 / m2

k = 28/14
 Dividing both numbers between 14 we have:
 k = (28/14) / (14/14)
 Rewriting:
 k = 2/1

k = 2
 Answer:
 
Zelie should have divided both numbers by 14.
