4/y - 5 = 5/2y
Multiply both sides by 2y
8 - 10y = 5
Subtract 8
-10y = -3
And divide by -10 to get y
y= 3/10

4 - 5y = 5/2y^2
0 = 5/2y^2 + 5y - 4
use the quadratic equation to get the rest

Solve,
(4/y) - 5 = (5/2y)
(4 - 5y)/y = 5/2y
2(4 - 5y) = 5
8 - 10y = 5
10y = 8 - 5
y = 3/10
y = 0.3

Just take the square root of pi divided by the value of the third derivative of the quadratic formula at a=-4, and that will give you the logarithm of the y value.

8333333=y
4/y-5/2y
4/y * 2 - 5/2y =8/2y - 5/2y =3/2y 5/ 3/2y
1.66666667/2y
2y=1.6666667/2
y=.8333333333

you should really do your own homework. if you dont then you'll be sorry later on because you wouldn't have learned anything.
