First you must convert the denominator to an equal number by finding a same multiple, in this case it is 12. So the factions convert to 3/12 and 8/12. Now add the two, resulting in 11/12. So the answer is 11/12
Answer:
y=3
Step-by-step explanation:
y + 3 = –y + 9
Add y to each side
y+y + 3 = –y+y + 9
2y+3 = 9

2y+3-3 = 9-3
2y = 6
Divide by 2
2y/2 = 6/3
y =3
