    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

    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
