    Hi,

    If anyone has the P3 Heinemann Book could they talk me through question 17 on page 152 (exercise 5B) since I'm having lots of trouble with it. I've managed OM and OX of part (a) but can't manage OY, which also messes up the rest of the question.

    Any help greatly appreciated!

    OY is OX + XY
    This is traslated as:
    OY = 3/4 (b) + 1/5 (XA)
    OY = 3/4 (b) + 1/5 (XO + OA)
    OY = 3/4 (b) + 1/5 (- 3/4 (b) + (a))
    OY = 3/4 (b) - 3/20 (b) + 1/5 (a)
    OY = 1/5 (a) + 3/5 (b)

    Hopefully this will help you carry on dude!
