Solve the inequality: 3x + 7 ≤ 1.
Note
Subtract the constant from both sides to get 3x ≤ -6. Because 3 is positive, dividing by 3 keeps the inequality direction unchanged. So the solution is x ≤ -2. 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 ≤ -2, which matches the calculation or reasoning shown.
