If a-b=b-3=6 what is the value of a

A-b = b-3 = 6

Now, we know that b-3 = 6

b-3 = 6

+3 + 3

b=9

So, we only know that b = 9

Now, we apply it to one equation to solve for a.

a-9 = 6=6

a-9=6

+9 + 9

a = 9+6

a = 15

Final answer: The value of a is 15.

Now we shall check our work.

15-9 = 9 - 3 = 6

6=6=6

Our answer a = 15 is correct!

6+3=9 so b is 9. 6+9=15 so a is 15. 15-9=6=9-3=6

The value of a is 15.
