Simplifying -5(s + -30) = -10
 Reorder the terms: -5(-30 + s) = -10 (-30 * -5 + s * -5) = -10 (150 + -5s) = -10
  Solving 150 + -5s = -10 Solving for variable 's'.
 Move all terms containing s to the left, all other terms to the right.
  Add '-150' to each side of the equation. 150 + -150 + -5s = -10 + -150
 Combine like terms: 150 + -150 = 0 0 + -5s = -10 + -150 -5s = -10 + -150
 Combine like terms: -10 + -150 = -160 -5s = -160 Divide each side by '-5'. s = 32
 Simplifying s = 32
First you must isolate the variable s. Divide both sides by -5. Then add 30 to both sides to isolate s.

s-30=2

s=32
