- Division Property of Equality
- Addition Property of Equality
- Subtract Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
16 < -2(x + 4)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -2: 16 < -2x - 8
- Add 8 to both sides: 24 < -2x
- Divide -2 on both sides: -12 > x
- Rewrite: x < -12
Here we see that any number <em>x</em> smaller than -12 would work as a solution to the inequality.
