    x=5 - x
    ------ +1 The dashed line is divide. so x=5-x divided by 2 and there is a 1 added 2 on next to it. I think its 2.3 recurring, my sister thinks its 2 who is right or are both of us wrong?

    Is this the question?

    \displaystyle x =  \frac{5-x}{2} + 1

    If that is the question then your answer is correct.

    If it isn't then try to write out the question with brackets e.g. x = [(5-x)/x] + 2

    If you mean solve  \displaystyle x= \frac{5-x}{2} + 1 then the answer is  x=\frac{7}{3} so you are correct.
    It's important to be able to solve these simple equations for yourself quite quickly.

    If you wouldnt mind would you mind telling me if the answer to this question is 9 or not.A piece of card, 7 cm by 11 cm, has a square hole cut out of it. A second piece of card 8cm by 13cm, has four
    square holes, the same size as the first, cut out of it. The area of card left is the same in each case.What is the side length of the hole?
