Complete the square for x and y.
7x^2 + 3y^2 - 28x - 12y = -19
7x^2 - 28x + 3y^2 - 12y = -19
7(x^2 - 4x) + 3(y^2 - 4y) = -19
7(x^2 - 4x + 4) + 3(y^2 - 4y + 4) = -19 + 28 + 12
7(x - 2)^2 + 3(y - 2)^2 = 21
(-2/3) (-1.6)
(−2)(−3602879701896397) / (3)(2251799813685248)
=7205759403792794 / 6755399441055744
=1.066667
The answer is -28
