The equation is given to be:
![5x+5y=5](https://img.qammunity.org/2023/formulas/mathematics/college/yp4u5ltlfjashe30oz6sjaxi69gfccylio.png)
To check if the ordered pair satisfies the equation, we need to substitute the values into the equation. If it yields a mathematically true solution, then the pair satisfies the equation.
The ordered pair is (5, -4).
Make the following substitution:
![\begin{gathered} x=5 \\ y=-4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/5gf45n64ca2145g1yuv28ov350xbgwrbix.png)
Substituting, we have:
![\begin{gathered} 5(5)+5(-4)=5 \\ 25-20=5 \\ 5=5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/2q1e3rd57sxhxtf9jb5fx2oophxc8mp5bi.png)
Since the mathematical expression is true, then this satisfies the equation and the ordered pair is a solution to the equation.
The correct option is YES.
