solve for s. -2(1 + 8s) = -3(2s + 4) s =

Explanation:

Step1: Expand both sides

$$ \begin{align*} -2(1 + 8s)&=-3(2s + 4)\ -2-16s&=-6s-12 \end{align*} $$

Step2: Add (16s) to both sides

$$ \begin{align*} -2-16s + 16s&=-6s-12+16s\ -2&=10s-12 \end{align*} $$

Step3: Add (12) to both sides

$$ \begin{align*} -2 + 12&=10s-12+12\ 10&=10s \end{align*} $$

Step4: Divide both sides by (10)

$$ \begin{align*} \frac{10}{10}&=\frac{10s}{10}\ 1&=s \end{align*} $$

Answer:

(s = 1)
