it gives me long dry headaches.
Solve the value equation
2/3x - 5/ - 8=8
I know I have to add that -8 to the right side of the equal sign.

With the slash, I don't know if the -8 is a divisor for the 5. If it is, you don't add 8 to both sides. If the slash was a typo, add 13 to both sides. Then multiply both sides by 3x.
@ psyDAG its lines like brackets this is a type of inequality problem and I solved part of it positive but when I use negatives to test its absolute value, everything falls apart.
ahhh, so you mean
2|3x-5| - 8 = 8
then
2|3x-5) = 16
|3x-5| = 8
3x-5 = 8 or -3x+5 = 8
3x = 13 or -3x = 3
x = 13/3 or x = -1
2|3x-5| - 8 = 8
then
2|3x-5) = 16
|3x-5| = 8
3x-5 = 8 or -3x+5 = 8
3x = 13 or -3x = 3
x = 13/3 or x = -1
I think the 8 at the right of the = must be either positive or negative. And solve both ways it made a little sense for me when 8 was positive. Not when it was negative
