What is the standard for of |3x - 8| - 4=0? 5 stars to best help

Please help, thanks!
what is |4x - 5| - 7 = 0 in standard form? |3x-8|=2??

Also ..Does this equation have a set notation solution { }?

|3x - 8 | - 4 = 0
|3x - 8 | = 4 (Since Modulus needs to consider both positive and negative values)
- (3x - 8) = 4 and (3x - 8) = 4
-3x + 8 = 4 and 3x - 8 = 4
-3x = 4 - 8 and 3x = 4 + 8
-3x = -4 and 3x = 12
x = 4/3 and x = 4.

b) |4x - 5| - 7 =0
|4x - 5| = 7
-(4x - 5) = 7 and (4x - 5) = 7
-4x + 5 = 7 and 4x = 7+5
-4x = 2 and 4x = 12
x = -2/4 = -1/2 and x = 3

3x-4=0
