Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-18s' to each side of the equation.
-6 + 8s + -18s = 18s + -18s

Combine like terms: 8s + -18s = -10s
-6 + -10s = 18s + -18s

Combine like terms: 18s + -18s = 0
-6 + -10s = 0

Add '6' to each side of the equation.
-6 + 6 + -10s = 0 + 6

Combine like terms: -6 + 6 = 0
0 + -10s = 0 + 6
-10s = 0 + 6

Combine like terms: 0 + 6 = 6
-10s = 6

Divide each side by '-10'.
s = -0.6

Simplifying
s = -0.6
