using substitution, what would be your first step to solve this system?

Answer:
Solve one of the equations for one of the variables
Explanation:
Given the system
[tex]\begin{gathered} 5r-s=5 \\ -4r+5s=17 \end{gathered}[/tex]To solve this system, the first step is to solve an equation from these two equation for one of the variables, either x or y.
Hence, the first option is correct.
