Answer:

Step-by-step explanation:

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

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

-18x > -36                            20x > 40

x < -36/-18                           x > 40/20

x < 2                                    x > 2

x < 2 OR x > 2
