  1. Now your question confuses me.

    Is the problem X+3/2=3 or (X+3)/2=3

    If it is X+3/2 = 3, then all you do is isolate the X by subtracting 3/2 from both sides leaving you with X=3/2 or 1.5

    Now if your problem is (X+3)/2 = 3, then all you do is isolate the X by multiply the 2 from both sides: X+3 = 6. Next you subtract 3 from both sides to isolate the X leaving you with X=3.

    Hope this helped.


  2. (x+3)/2=3

    x+3=6

    x=3

    x+(3/2)=3

    x=3/2

  3. x+3

    -----..=3

    ..2

    Multiply the whole equation by 2.

    x+3 = 6

    =x=6-3

    =x=3

    Check.

    (3) + 3 = 6

    Now take a wild guess if this will equal to 6. :P

    6=6

  4. Here it is:

    x + 3/2 = 3

    First, multiply 2 to both sides leaving x + 3

    x + 3 = 6

    Then subtract 3 to both sides so that x will be by itself.

    x +3 = 6

       -3   -3

    -------------

    x = 3

    Final answer is x = 3.

    Hope this helps. =)
