Answer: 
Step-by-step explanation:
To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[multiply first fraction by y+4 and second by y-8]
[distribute by FOIL]
[add numerator]
[combine like terms]
[factor out 2 from numerator]
Now we know that is the factored form after adding.
Answer:
6
Step-by-step explanation:
The main idea of how to solve it is to isolate the variable. Whatever you multiply, divide, add, or subtract on one side, you must do the same to the other side so that both sides are equal.
3(x-1) = 21
3(x-1) / 3 = 21 / 3
x - 1 = 7
+ 1 + 1
x = 6
