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.
