┃1/2x + 1/3┃= 2
1/2x + 1/3 = 2
6(1/2x) + 6(1/3) = 6(2)
3x + 2 = 12
3x + 2 - 2 = 12 - 2
3x = 10
3x/3 = 10/3
x = 10/3
x = 3 1/3

Just pretend those absolute value lines aren't there in this case:
1/2x=6/3-1/3
x=10/3
Absolute value makes a difference when an unknown (x) can be either positive or negative (like in the case od a square root etc). In this case it doesn't make a difference in how you solve for x.
For example distances in general tend to have the absolute value sign automatically on them since distance can never be a negative number. Here, you just ignore the absolute value and solve for x. You can even put the absolute value sign on your x, but it's not necessary.

hmmmm - not sure this is correct
subtract 1/3 from both sides (it's an equation)
1/2 x = 1 2/3
multiply both sides by 2
x = 3 1/3
is that what you mean by absolute value?

Can you use the |X| symbol instead of /x/ symbol please? You are getting me confused.
