Solve for x

-18x+21>-15 or 20x-13>27

All numbers between - 2 and 2, not touching - 2 or 2

Step-by-step explanation:

-18x+21>-15 simplifies to - 18x > 36, which in turn becomes 18x < - 36, or

x < - 2.

20x-13>27 simplifies to 20x > 40, or x > 2.

Then the solution set is

(-2, 2) : All numbers between - 2 and 2, not touching - 2 or 2.
