-10 = 9k - 40
1st Step: get rid of the -40 by adding 40 to each side of the equation:
-10 (+ 40) = 9k - 40 (+ 40)
30 = 9k
2nd Step: since 9 is being multiplied by k, get rid of the 9 by dividing both sides of the equation by 9:
30 / 9 = 9k / 9
3.33 = k
k = 3.33

-10=9k-40
-10+40=9k
30=9k
k=30/9

Add 40 to both sides.
30 = 9k
Divide both sides by 9.
30/9 = k
Simplify 30/9 by dividing top and bottom by 3.
10/3 = k
k = 3 and 1/3

Well you would :
40- the negative 10= negative 30
Then negative 30 divided by 9= k
K= negative 3.3
I think thats right :) Good Luck :)

Quick guess....
3.3 (or better, 3.33333e)
yeah, works like this
9 x 3.3 = 30
30-40 = -10

To find the value for k:
-10 = 9k - 40
-9k = -40 + 10
-9k = -30
k = -30/-9
k = 3.3333333333333333333
----------------------------------------------------------------------------------
The value of k is 3.3333333333333333333

The answer is 3.33 (not -3.33), but man, do your own homework!!!
If you don't do your homework now, you'll end up like . . . George W. Bush. Ugh! You don't want that, do you?
