Answer:
-7/8y²+3
Explanation:
It seems like we are just combining like terms here. Like terms have the same variable raised to the same power. We have three terms here: two of them are y² terms and one is just a 3, so we can combine those two like terms and then just add 3.
5/8y²-3/2y²= -7/8y²
Now we just plop the three on the end and we're done!
-7/8y²+3
Have a wonderful day!
