Question 2: here is triangle ABC. line DE is parallel to line AC.

What is m∠DBA + b + m∠CBE? Explain how you know (Please provide step by step for question 2.)

There is no question, there is just the answer.

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
