I need a stepbystep response cause I'm having a hard time understanding.

5 h – 9 = – 16 + 6 h Add 9 to both sides
5 h – 9 + 9 = – 16 + 6h + 9
5 h = – 7 + 6h Subtract 5 h to both sides
5 h  5 h =  7 + 6 h  5 h
0 =  7 + h Add 7 to both sides
0 + 7 =  7 + h + 7
7 = h
h = 7
Proof :
5 h – 9 = – 16 + 6 h
5 * 7  9 =  16 + 6 * 7
35  9 =  16 + 42
26 = 26 
Thank you, this makes a lot of sense.
