Answer:
4th option
Step-by-step explanation:
Given
-
← expand denominator using FOIL
=
- 
Since the denominators are common, then subtract the numerators
= 
For eliminating you need to have a variable that cancels the other out and in this case 2x and -2x do. Then you want to take -3y+9y and add the numbers after the equal sign. -9+3
6y-10=y+25
subtract y from both sides
5y-10=25
add 10 to both sides
5y=35
divide both sides by 5
y=7
