Question 1062359
The system of equations I need to solve is:
7x - 8y = 24
xy^2 = 1 
In the second, it's not (xy)^2, but just the y is squared. I get to substitution and replace y in the second equation with y = (7/8)x + 3 and end up with (23/32)x^3 + (21/4)x^2 + 9x - 1 = 0.
--------------
7x - 8y = 24 --> y = (7/8)x -3  ***  not +3
x*(7x/8 - 3)^2 - 1 = 0
x*(49x^2/64 - 21x/32 + 9) -1 = 0
49x^3/64 - 21x^2/32 + 9x - 1 = 0
Multiply by 64
49x^3 - 42x^2 + 576x - 64 = 0

The only real root I see is ~ 0.111905 (by graphing)
