: Rational expressions with different denominators
2x/x^2-9+3x/x^2+4x+3
I am confused on how to find a common denominator. I know for the first one it could be either 3x(x-3) or (x-3)(x+3) for the second denominator i can only think of (x+3)(x+1) i just don't know which denominator is missing what.

Question 203479: 1. Solve by substitution or elimination method:
3x – 2y = 26
-7x + 3y = -49
2. Solve by substitution or elimination method:
4x – 5y = 14
-12x + 15y = -42
3. Solve by substitution or elimination method:
-2x + 6y = 19
10x – 30y = -15
Second part of problems:
1. Plot the graph of the equations 2x - 3y = 5 and 4x - 6y = 21 and interpret the result.
2. Plot the graph of the equations 4x - 6y = 12 and x - 5y = 10 and interpret the result.
3. Plot the graph of the equations 8x - 4y = 12 and -4x + 2y = -6 and interpret the result.

Question 203585This question is from textbook
: 52) a+4 a+4
------=-----
2 a
I can't remember how to figure this one out and the examples from the book aren't making it any easier for me. I am not sure if i am suppose to find a common denominator which i would think would be 2a and then times each one by the one that would make the denominator 2a.
thank you so muchThis question is from textbook
