    Well on my text book, the exercise is 7.4 (not relevant but w/e) and the question is "Form an equivalent equation to each of the following by performing the operation given in brackets."

    Now the first question.

    "x-4=1 (+7)"

    Note: the "x" is a pronumeral.

    I'm expected to hand this in tomorrow and I have no idea what to do so if someone can help me by explaining how to do it, I will be incredibly grateful.

    Thanks in advance.

    Just add 7 at both sides of the 'is equal to' sign...

    As the poster above said, add 7 to each side.

    The new equation would be: x + 3 = 8

    Yeah, I think he would have preferred the answer over a month ago, when he asked. Nice bump. [​IMG]

    In fact, from a glance at your profile, you registered a week before then. FAIL.

    actually i think there is a proof for 1+1=2 which is around 500 pages iirc.

    it's easier to prove that .999... = 1

    (1 + 1) x 0 = 2 x 0
    -> 1 + 1 = 2

    The actual proof is proving that 2>1 then doing something else which I can't remember.
    I have it in my notes somewhere it's 1 page not 500 [​IMG]

    There's your proof.

    So that means that:

    (685944.543 + 1043255252.435252) X 0 = 2 X 0
    -> 685944.543 + 1043255252.435252 = 2

    I highly doubt it.
