What is the solution to this -28=3+8(h-

show work , if also explain why so (:
you (:

-28 = 3 + 8(h-9)
-28 = 3 + 8h - 72    (distributive property a(b-c) = ab - ac)
-28 = -69 + 8h        (combining like terms ( 3 - 72))
 41 = 8h                  (adding 69 on both sides to isolate 8h)
 /8     /8                   (dividing coefficient (8) on both sides to isolate h)
 5.125 = h

Therefore h = 5.125
