4. -2s + 3 = 5s + 24

Explanation:

Step1: Move terms with (s) to one side

Subtract (5s) from both sides: (-2s - 5s+3 = 5s - 5s+24), which simplifies to (-7s + 3=24).

Step2: Isolate the term with (s)

Subtract (3) from both sides: (-7s+3 - 3=24 - 3), so (-7s = 21).

Step3: Solve for (s)

Divide both sides by (-7): (s=\frac{21}{-7}).

Answer:

(s=-3)
