    None,

    a=1/2

    Step-by-step explanation:

    Lets group together 'a' terms in one side of equations and lone terms on the other.

    To do this, simply sum 'a' to both sides of equation, and also, subtract - 1 (lone term).

    3a+a=3-1

    this leads to

    4a=2

    Where we obtain a=1/2
