@zepdrix please help!

Answer 3

Solve for Bc?

Answer 4

\[\Large\rm 0.1=\frac{B_c}{100+B_c}\]

Answer 5

Let's multiply both sides by 10, so we don't have to deal with a decimal value.\[\Large\rm 1=\frac{10B_c}{100+B_c}\]

Answer 6

Multiply both sides by (100+Bc),\[\Large\rm 1(100+B_c)=10B_c\]\[\Large\rm 100+B_c=10B_c\]
Understand how to solve it from there?
Any steps confusing?

Answer 7

I understand so far. next step is not sure.

Answer 8

Combine like terms.
Get the B's on the same side.

Answer 9

Bc=10Bc-100?

Answer 10

You moved the 100 to the other side....
You want your B's on the same side.
You don't want to move the 100.

Answer 11

Subtract B from each side.

Answer 12

ok.
100-10Bc=Bc?
