    Answer:  3x — 5 x + 9

    Step-by-step explanation: = x (3–1) + (–5 + 9)

                                                 = x (2) + 4

                                                 = 2x + 4

                                      putting x =3

                                               = 2 (3) + 4

                                               = 6 + 4

                                               = 10
