inside the () becomes -3+b
now inside [] 2a-3+b multiplied by 2
-2[2a-3+b]=-4a+6-2b
what is left
4a-{6b-4a+6-2b}
multiply through by -
4a-6b+4a-6+2b
combine like terms
8a-4b-6

Work from the inside to the outside taking one step at a time.
-----------------------
4a-{6b-2[2a-(3-b)]}
---
= 4a-{6b-2[2a-3+b]}
----
= 4a-{6b-4a+6-2b}
---
= 4a-{4b-4a+6}
---
= 4a-4b+4a-6
---
= 8a-4b-6
