6y-y3 = 3
Lets start by putting the known number on the other side. Y3 -7500y=125000. There is your start. Take it from here.
-y3 + 7y3
x3-y3
The Yttrium atom (Y) has 39 electrons. The ion Y3+ will have lost 3 electrons, so the Y3+ ion will have 36 electrons.
72
27-y3 factored completely = 24
X2+Y3+15 All you can do is simplify it.
No
y times y times y (or y3)
30
12x2 - 24x + 9y
