To solve this equation, we need to isolate the variable on one side of the equation.

Starting with the given equation:

(19x^2 + 28y^2) = 2023

First, we can subtract 2023 from both sides of the equation:

19x^2 + 28y^2 - 2023 = 0

Now, we can divide both sides of the equation by the common factor of 19:

x^2 + (28/19)y^2 - 2023/19 = 0

Simplifying further, we have:

x^2 + (28/19)y^2 - 106.58 = 0

This is the simplified form of the equation.
