Subtract the constant from both sides to get 7x ≤ 28. Because 7 is positive, dividing by 7 keeps the inequality direction unchanged. So the solution is x ≤ 4. Solve an inequality much like an equation: isolate x step by step. Since the division here is by a positive number, the inequality sign stays in the same direction. The final answer represents a range of values, not just one value. The correct answer is x ≤ 4, which matches the calculation or reasoning shown.
