    -1=1/2a+9

    move + 9 to the other side

    sign changes from + 9 to - 9

    -1-9=1/2a+9-9

    -1-9 = 1/2a

    -10 = 1/2a

    Mutiply both sides by 2/1

    (-10) (2/1) = 1/2a*2/1

    Cross out 2 and 2, divide by 2 and becomes 1

    Cross out 3 and 3, divide by 3 and becomes 1

    1*1*a = a

    a = - 20

    Answer: a = - 20
