Question

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

Answer 1

Solve one of the equations for one of the variables

Step-by-step explanation:

Given the system

`\begin{gathered} 5r-s=5 \\ -4r+5s=17 \end{gathered}`

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.
