A.
–21

B.
–5

C.
5

D.
21

Answer 1

(17+h)+(-9) = 17+(5+(-9))
solve first the innermost parenthesis of the right side making it
(17+h)+(-9) = 17+(5-9)
(17+h)+(-9) = 17+(-4)
(17+h)+(-9) = 17-4
(17+h)+(-9) = 13
add both sides of the equation with 9 so that -9 of the left side will be eliminated
or you just have to transpose it
(17+h)+(-9+9) = 13+9
17+h=22
subtract 17 to both sides of the equation
-17+17+h=22-17
h=5
