24=4 (h/2 - 7)?

Question

please help me find the answer, i can 't figure it out I've been working on it for half an hour. I know there 's probably something very simple i forgot but if you know how to solve this please let me know

Answer 1

24 = 4 (h/2 -7)

6 = (h/2 -7).....................{ divided both sides by 4 }

13 = h/2 .........................{ added 7 to both sides }

26 = h ............................{ multiplied both sides by 2 }

Answer 2

6 = h/2 - 7
h/2 = 13
h = 26
