    Answer:

    a = 3

    Step-by-step explanation:

    1) Simplify 5a – 9 + a to 6a – 9.

    6a - 9 = 9

    2) Add 9 to both sides.

    6a = 9 + 9

    3) Simplify 9 + 9 to 18.

    6a = 18

    4) Divide both sides by 6.

    a = \frac{18}{6}

    5) Simplify 18/6 to 3.

    a = 3

    Therefor, the answer is, a = 3.
