i know the first step is divide by b but I'm stuck what to do next ?

@Mertsj come here

5. Mertsj

Then multiply both sides by the common denominator which is cd

6. Mertsj

|dw:1358799281945:dw|

7. Mertsj

Add c to both sides and then factor out the c.

8. Mertsj

$\frac{acd}{b}+c=d$

9. Mertsj

$c(\frac{ad}{b}+1)=d$

10. Mertsj

$c(\frac{ad+b}{b})=d$

11. Mertsj

$c=\frac{bd}{ad+b}$
