Step-by-step explanation:

To solve this, we can use a system of equations.

First we can set up a system of equations like this

and

Next we will use substitution to solve for one of the values. We can solve the second equation such that

Now we can substitute this into the first equation for s

Now we can solve for r

Now we can plug this value into the second equation to get the value for s

Now we can plug these values into the first equation to make sure we have the right values
