Answer and Step-by-step explanation:


\Huge\boxed{B=-3}

Step 1 : Simplify both sides of the equation :


-8(8+4b)=20-4b


(-8)(8)+(-8)(4b)=20+-4b (By Distributing)


-64+-32b=20+-4b


-32b-64=-4b+20

Step 2 : Add
4b to both sides :


-32b-64+4b=-4b+20+4b


-28b-64=20

Step 3 : Add
64 to both sides :


-28b-64+64=20+64


-28b=84

Step 4 : Divide both sides by
-28 :


(-28b)/(-28)=(84)/(-28)


b=-3

That should be you're final answer!
