-18r + 6s = -3 solve for s

To solve for s, we need to isolate the variable s on one side of the equation.

-18r + 6s = -3

First, let's move the term -18r to the right side by adding 18r to both sides of the equation:
6s = 18r - 3

Next, we want to isolate s by dividing both sides of the equation by 6:
s = (18r - 3) / 6

So the solution for s is s = (18r - 3) / 6.
