s = 4

To get this, substitute r in the equation for ten:

3(10) = 10 + 5s

Then perform the two step equation:

30 = 10 + 5s

Subtract ten from both sides

20 = 5s

Divide by five on both sides

4 = s

Hope this helps!

3r = 10 + 5s, when r = 10

Plug in r = 10 into equation 3r = 10 + 5s

3(10) = 10 + 5s

30 = 10 + 5s

5s = 20

s = 4

Answer: s = 4
