Solution:

3x + 15 + 2x + 12 = 15         (Distributive Property of Multiplication
                                               over Addition)

3x + 2x + 27 - 27 = 17 - 27    (Addition Property of Equality)

5x = -10

(1/5) (5x) = (-10) (1/5)            (Multiplication Property of Equality)

x = -2
