solve for s.\n2s + 4 = 5(-4 - 2s)\ns =

Answer:

(-3)

Explanation:

Step1: Expand the right - hand side

$$2s + 4=5(-4 - 2s)$$ $$2s + 4=-20-10s$$

Step2: Move the terms with (s) to one side

Add (10s) to both sides: $$2s+10s + 4=-20-10s+10s$$ $$12s + 4=-20$$

Step3: Isolate the term with (s)

Subtract (4) from both sides: $$12s+4 - 4=-20 - 4$$ $$12s=-24$$

Step4: Solve for (s)

Divide both sides by (12): $$s=\frac{-24}{12}$$ $$s = - 3$$
