  1. 5-8b+6-2B=61

    Combine like terms:

    -8b - 2b = 61 - 5 - 6
    -10b = 50
    b = -5

    Follow this pattern to solve the other problems. We'll be glad to check your answers.

  2. for #2 i keep getting the answer -4.5 and i check and its wrong this is what i did

    4x-8x=-4x
    6-9=-3

    -4x--3=21
    18=21
    x=-4.5

    are the steps i did wrong and when i plug in the number i get 3 as an answer instead of 21

  4. As a non-mathematician, I get confused by a lot of numbers, too. <g> But here's the way to do 2.

    4x-6-8x-9=21
    -4x - 6 - 9 = 21
    -4x = 21 + 15
    x = -9

    The answer for number 3 is 3. Can you keep working this problem until you get the right answer?

  7. When you do the problem or the proof, please be sure you don't leave out any parts of the original problem. (I kept leaving a part of the original problem out until I went back and triple checked.)
