Answer 2

Answer:

The answer to your question is  r = 3

Step-by-step explanation:

                               2r  - 15 = - 9r + 18

Process

1.- Add 9r in both sides

                              2r + 9r - 15 = - 9r + 18 + 9r

2.- Simplify

                                    11r -15 = 18

3.- Add 15 to both sides

                                   11r - 15 + 15 = 18 + 15

4.- Simplify

                                   11r = 33

5.- Divide both sides by 11

                                   11/11 r = 33/11

6.- Simplify and result

                                   r = 3
