# How to work out this algerbraic fraction? watch

1. 6- (x-1 over 2) = 3x -11

x equals 5 but I can't work out how you actually get 5...
any help would be great thanks x
2. What have you tried?

It would help to multiply everything by 2.
3. 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!)
