First simplify it, making it ca+cb-d=f. Then move cb and -d to the other side, which flips their signs, making the equation ca=f+d-cb. Then divide the left side by c to get rid of it and the right side to make it even, which gives you a=f+d-cb/c
Distribute the c so you get
Ca+cb-d=f
Then subtract cb from the first problem.
Ca-d=f-cb
Then add d from the first problem
Ca=f-cb+d
Then divide c from each side
Ca. =. F-cb+d

So you should get
A= f-cb+d/c
Ca+cb-d=f
Then subtract cb from the first problem.
Ca-d=f-cb
Then add d from the first problem
Ca=f-cb+d
Then divide c from each side
Ca. =. F-cb+d

So you should get
A= f-cb+d/c
