#1
5h – 9 = –16 + 6h
-h = -7
h = 7

#2
4x + 4 = 9x – 36
-5x = -40
x = 8

#3
7x + 5 = 4x + 5 + 3x
7x+5 = 7x+5
true for all x

#4
place a solid dot at x = -2

#5
k < 0

#6
q – 12 ≥ –13
q >= -1

#7
12p < 96
p < 8

#8
g/–5 < –18
g > 90

#9
n-6 >= 2
n >= 8

#10

1) 5h ¨C 9 = ¨C16 + 6h
-9+16 = 6h-5h
7 = h

4x + 4 = 9x ¨C 36
36 +4 = 9x-4x
40 = 5x

8 =x
5) k < 0
6) q ¡Ý ¨C1
7) p < 8
8)g > 90
9)n ¨C 6 ¡Ý 2; n ¡Ý 8
