Comparing Solutions of a System of Equations

Consider the equations defined as follows:

1. $$2x - 3y + 6 = 0$$

2. $$5x + 4y - 20 = 0$$

Solve for the values of $$x$$ and $$y$$ from these equations. Define Quantity A as the value of $$x$$ and Quantity B as the value of $$y$$. Determine the relationship between Quantity A and Quantity B.
