To solve the inequality 2x - 3 ≥ 4x + 21, we can start by subtracting 2x from both sides:
-3 ≥ 2x + 21
Next, we can subtract 21 from both sides:
-24 ≥ 2x
Finally, dividing both sides by 2 (and flipping the inequality sign because we are dividing by a negative number), we get:
x ≤ -12
Therefore, the correct solution is x ≤ -12.
Solve.
