1. The problem involves two expressions: $x - 8$ and $y - 6$. 2. These expressions represent values shifted from $x$ and $y$ by 8 and 6 units respectively. 3. If the goal is to find a relationship or solve for $x$ or $y$, more information or an equation is needed. 4. For example, if you want to solve $x - 8 = 0$, add 8 to both sides: $$x - \cancel{8} + \cancel{8} = 0 + 8$$ which simplifies to $$x = 8$$ 5. Similarly, for $y - 6 = 0$, add 6 to both sides: $$y - \cancel{6} + \cancel{6} = 0 + 6$$ which simplifies to $$y = 6$$ 6. Without additional context or equations, these expressions represent values shifted from $x$ and $y$ by constants 8 and 6 respectively.
