1. 4 < 7 Multiply both sides by 3 , then by 2, then by 4, then by 9 4 < 7
*3 *3
12 < 21
24 < 42
96 < 168
864 < 1512
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
11 > -2
+3 +3
14 > 1
17 > 4
-4 -4
14 > 0

3. -2 < -2 Subtract 6 from both sides, then 8, and then 2
-2 < -2
-6 -6
-8 = -8
8 8
0 0-2
=
-2 -2
4. -4 < 8 Divide both sides by -4, then by -2

-4 < 8
-4 -4
0 > -12
-2 -2
2 < 10
