What have you tried?
It would help to multiply everything by 2.

As nuodai's post says, if you get rid of the fraction (x-1 over 2) by multiplying the equation by 2, then you should get:
12-(x-1) = 6x - 22 (next step is to multiply out the brackets)
12-x+1 = 6x - 22
now if you collect like terms (i.e. values of x on 1 side and number/answer on other side) then simplify
7x = 35 (then dividing 35 by 7....you get answer!)
