Answer:
b=10,000
Step-by-step explanation:
[tex]9,000-b=-11,000+b[/tex]
Regroup terms
[tex]9,000-b=b-11,000[/tex]
Add b to both sides
[tex]9,000-b+b=b+b-11,000\\9,000=2b-11,000[/tex]
Add 11,000 to both sides
[tex]9,000+11,000=2b-11,000+11,000\\9,000+11,000=2b[/tex]
Simplify by adding
[tex]20,000=2b[/tex]
Divide both sides by 2
[tex]\frac{20,000}{2}=\frac{2b}{2}\\ \\10,000=b[/tex]
Switch sides
[tex]b=10,000[/tex]
Done.
Answer:
b=10000
Step-by-step explanation:

9000=-11000+2b
add -11000 on both sides
20000=2b
divide by 2 on both sides
b=10000
