My 6th is the sum of the forth and fifth etc until I have 10 numbers (if I start with 2 and 3 they would be 2, 3, 5, 8, 13, 21, 34, 55, 89, 144) Add these 10 numbers together.I can find the answer in my head before you can using a calculator using algebra.

Question 535794: I have an exam in just a little more than an hour. I am going over my review for the exam and there are 2 problems that I have the answers for, because they have given us that but I need to know how to go about solving the probelems. Anyone's help is greatly appreciated!!!
_x+4_ = _x+10___
x-3 x+2
Not sure if this makes any sense... I am not sure how to type this up.. It is fractions. x+4 is over x-3 and then it is = in the middle with x+10 above x+2.
The other one that I am struggling with is this
__5__ + _3__ = 1
3x x
This is the same it is a fraction but instead of it being a fraction at the end it is an equals sign with a 1. Thanks so much!
