  1. 7. does not look right. Dividing by -1/4 is the same as multiplying by -4.

    10. Too many = signs in what you wrote.
    7x + 28 = 9x - 18
    2x = 46
    x = 23 should be written separately

    11. Two minuses make a plus, but that is not what you did

    13. There are too many = signs again.

  2. on 11 i was trying to write them as fraction i was afriad you would not be able to read them so it reads subtract -5/26-(-3/13)= -11/26?

    on 13. the problem is solve using principles together 7x-7=13+12x

    my answer is x=4?
    would that be right?

    7. simplify [15/(-3)]/ (-1/"over"4)=8?

  3. 12. is -13? i was not sure if you could see the negative sign...thank u so much!

  5. 7. is still wrong
    11. is still wrong
    You don't need to write "over".
    13. is correct

  6. algebra is also spelled incorrectly

  7. 11. subtract -5/"over"26- (-3/"over"13)= -8/39?

    7. simplify [15 divided by(-3)]divided by (-1/"over"4)=1.25?

  8. Get rid of the "over". One doesn't write algebraic expressioons that way.

    -5/26 -(-3/13) = -5/26 + 6/26 = 1/26

  10. were these right?

    7. simplify [15/(-3)]/ (-1/4)=1.25?

    12. is -13? i was not sure if you could see the negative sign...thank u so much!
