I believe y equals 4.
9/4y - 12. = 1/4y - 4
+ 12. +12
9/4y. = 1/4y + 8
- 1/4y. - 1/4y
8/4y. = 8
2y. = 8
2. 2
Y = 4
<span>a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

I think that the answer should be around 2.55
1. (x, y) = (7, -12)
2. x = 1, x = 2 are both solutions
