You must register or log in to post a message. I would say the parametric solution of a=t, b=20-4t is the most complete 'solution', again as GIS said. You can get the solution outlined in B if t=4, and if you substitute t=2 you get b=20-4(2)=20-8=12, which is not the correct b for option C to be a valid solution. Let me give you a problem, solve for x and y in the following system of equations: x+y=1, x^2+y^2=1 If that is too easy, how about swapping the 2 for 3, or 4?   4a-2+b=18 Solve for a and b. Hint: You can use mental math for this one. Choose the correct letter. A. a=4, b=2 B. a=4, b=4 C. a=2, b=4   Chris3000     And i shall take my leave.

As for part 2, I assume you want us to find a general formula for the Fibonacci sequence and then substitute n=1/2 in. I'm not sure if you want just the real part or both real and imaginary. Suffice it to say that the expression is pretty horrible looking either way - so I will use phi for the Golden Ratio to shorten it as much as possible. Only my answer is below because it's a lot of working out to post.
Part 2:
