solve for s.\n7s + 2(4s - 10) = 10\ns =

Explanation:

Step1: Expand the expression

$$ \begin{align*} 7s + 2(4s - 10)&=10\ 7s+8s - 20&=10 \end{align*} $$

Step2: Combine like - terms

$$ \begin{align*} (7s + 8s)-20&=10\ 15s-20&=10 \end{align*} $$

Step3: Isolate the term with (s)

Add (20) to both sides of the equation: $$ \begin{align*} 15s-20 + 20&=10+ 20\ 15s&=30 \end{align*} $$

Step4: Solve for (s)

Divide both sides by (15): $$ s=\frac{30}{15}=2 $$

Answer:

(2)
