The only way I can make this work out is if you meant:



and



and that ABC is complementary to CBD.

Under those presumptions:



Solving for yields . I tried several common errors and was unable to reproduce your wrong answer; hence I have no idea what you did wrong. Repost and show ALL of your work.

I do have some advice for you though. One of the secrets to success in mathematics is attention to detail; a characteristic sadly lacking in your post. In the first place you have very little punctuation, inappropriate capitalization, incorrect operation sign in your second algebraic expression, failure to use parentheses -- you get the point. If you are laboring under the gross misapprehention that "this is math, I don't have to care about correct and understandable English" then allow me do disabuse you of any such notion. Mathematics requires MORE, not less, precision of expression.
