    To find the answer you do:

    5a-3=8a+6

    5a-8a-3=8a-8a+6

    -3a-3=6

    -3a-3+3=6+3

    -3a=9

    -3a/-3=9/-3

    a=-3

    So a is equal to - 3.

    Subtract 5a from both sides

    -3=3a+6

    Subtract 6 from both sides

    -9=3a

    Divide by three

    a = - 9/3 (which is - 3)

    Remember what you do to one side you must do to the other
