Answer:
For the first one, you get x<7.
For the second one, you get x >_ 11
Step-by-step explanation:
For the first one: -2x - 2 > -16
Step 1. Add 2 to both sides.
-2x - 2 +2 > -16 + 2
-2x > -14
Step 2. Divide both sides by -2 and switch the sign
-2x/-2 > -14/-2
x < 7
For the second one: 2x - 1 >_ 21
Step 1: Add 1 to both sides
2x -1 +1 >_ 21 + 1
2x >_ 22
Step 2: Divide both sides by 2
2x/2 >_ 22/2
x >_ 11
