K - 10/2 = -7
K - 5 = -7    (perform the indicated division)
K = -2    (add 5 to both sides of the equation)

Perhaps you intended this.
(K -10)/2 = -7    (parentheses are used to identify the numerator)
K -10 = -14    (multiply both sides of the equation by 2
K = -4    (add 10 to both sides of the equation)

K-5=-7
k-5+5=-7+5
k=-2

to check your work you -2 back into the problem.

-2 - 5=-7
-7=-7

when they equal each other you have the correct answer...
