The answer is y=3
To show my work here.
1. regroup terms ( y + 3 = 9 - y)
2. subtract 3 from both sides ( y = 9 - y - 3)
3. simplify 9 - y - 3 to 6 - y ( y = 6 - y)
4. add y to both sides ( y + y = 6)
5. simplify y + y to 2y (2y = 6)
6. divide both sides by 2 ( y = 6/2)
7. simplify 6/2 to 3 ( finally y = 3)
Hope this helps, and if it does don't forget to mark as brainliest.
