3/2 OR 1 1/2
Step-by-step explanation:
Collect like terms, meaning combine both y's. You should have something like this afterwards.
6y = 9
Now that you have that divide the 6 on both sides so Y is by itself!
Your answer is now 3/2.
You put the whole number on top of 1, it doesnt change its value. then you simplify across like in a butterfly only if needed then you multiply across from left to right.
