SOLUTION: How would I solve this? The example on My Math lab said to multiply 10 and 6...why?
|8x-3|=6
-----
10
(the absolute value bars are around 8x-3 over 10.
Thanks!

If the fraction [(8x-3)/10] is in the absolute value sign
you get two equations:
(8x-3)/10 = 6 and (8x-3)/10 = -6
8x-3 = 60 or (8x-3)= -60
8x = 63 or 8x = -57
x = 63/8 or x = -57/8
------------------------------
If the 10 is not in the absolute value sign you get
|8x-3| = 60
Then you get:
8x-3 = 60 or 8x-3 = -60
8x = 63 or 8x = -57
8x = 63/8 or x = -57/8
================
Either way you get the same result.

= 6
To remove absolute value bars, you must make and solve two
separate equations.
= +6 and }} = -6
Multiply both sides of both equations by 10 to clear of fractions:
8x-3 = 60 and 8x-3 = -60
Add 3 to both sides of both equations:
8x = 63 and 8x = -57
x = and x =
