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.

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 7x7=13+12x
my answer is x=4?
would that be right?
7. simplify [15/(3)]/ (1/"over"4)=8?

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


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

algebra is also spelled incorrectly

11. subtract 5/"over"26 (3/"over"13)= 8/39?
7. simplify [15 divided by(3)]divided by (1/"over"4)=1.25?

Get rid of the "over". One doesn't write algebraic expressioons that way.
5/26 (3/13) = 5/26 + 6/26 = 1/26


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!
