    Answer:a=-7

    Step-by-step explanation:The given equation is 3 (a-7) = 6a

    Using distributive rule we have:

    3a-21=6a

    21 is subtracted to 3a. We always perform the opposite operation both sides.

    Opposite of subtraction is addition

    Adding 21 both sides

    3a=6a+21

    Subtracting 6a both sides:

    3a-6a=21

    -3a=21

    Dividing both sides by - 3 we have

    a=-7.
