    Hey, I got my results at 5 to 9 this morning....
    4A*s n 7As, I'm a bit dissapointed...
    and before you have a go i will never ever deny that these results aren't fantastic but i was a bit dissapointed because i got As in Biology and Physics and htey were subjects in which i was confident of an A* (ie because after the exam my teachers said theyd b flabbergastd if i didn't) And I got an A* in Spanish which i thought was odd because I HATE spanish n subjects i wanted the A*s in i didn't get......

    Neway... I aint denyin theyre good results and well done to absolutely everybody!!!!!!!!!!!!!!!!!!!!!!! !1

    BMO questions?
    Yeah,I understood the first one,solved some of it,but hgot confused by the 1000 different letters but the second one,god knows,I didn't even get the answer

    cant u follow my working? there is a flaw in my working which occurs from the step "now we have" to "it follows" basically i skipped to show some more working by substituting a=c+2, into other equations ot get more factorised equations, the answers r correct...

    the second problem requires some knowledge of diophontine equations topic..which is solving equations where the number of unknowns are greater than equations provided in positive integers...

    Well in question 1,I didn't understand from it follows
    a-1=1 => a=2
    I didn't understand how you got that from (a-1)(d-b)=3??! :confused:
    Question 2,I didn't understand anything*LOL*

    from "now we have" two equations if u equate them u get:

    a-1=c+1
    a=c+2

    use the same principle to get:

    d=3-2b

    now if we substitute these into original equations u get:

    1. ab + c + d = 3
    given that c = 2 - a and d = 3 - 2b

    ab + 2 - a + 3 - 2b = 3
    ab - a - 2b = -2

    given that (a - 1)(b - 1) = ab - a - b + 1

    (a - 1)(b - 1) - b - 1 = -2
    (a - 1)(b - 1) = b - 1
    a - 1 = 1
    a = 2

    taking this value of a and your new value of c subsitute these in the original equations.
