First of all - you have written a function with 3 variables, namely, X (caps), x and y. I am assuming here you meant 'x' and 'X' are same. You need write those consistently.The problem is: X/2 - 2x + 2y/ 4y
It says to express as a single fraction in the simplest form. Do I need to find a common denominator like a regular fraction without X's or y's?
Before finding a common denominator you should try to reduce. Since variables are place holders for numbers then yes, you do have to get common denominators (after you reduce).The problem is: X/2 - 2x + 2y/ 4y
