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
5h – 9 = –16 + 6h
