Answer:
[tex]B=\frac{A}{2(C+D)}[/tex]
Step-by-step explanation:
[tex]A=2BD+2BC[/tex]
We can also write this by taking out 2B common:
[tex]A=2B(C+D)[/tex]
Dividing both sides by C+D;
=> [tex]2B=\frac{A}{C+D}[/tex]
Dividing both sides by 2;
=> [tex]B=\frac{A}{2(C+D)}[/tex]
Hence, the value of B is :
[tex]B=\frac{A}{2(C+D)}[/tex]
