Math Problem Statement

Solve -2x - 6 > 3x + 14.

Solution

Let's solve the inequality step by step:

The inequality given is: 2x6>3x+14-2x - 6 > 3x + 14

Step 1: Move the 3x3x term to the left side by subtracting 3x3x from both sides:

2x3x6>14-2x - 3x - 6 > 14 5x6>14-5x - 6 > 14

Step 2: Move the 6-6 to the right side by adding 6 to both sides:

5x>14+6-5x > 14 + 6 5x>20-5x > 20

Step 3: Solve for xx by dividing both sides by 5-5. Remember that when you divide or multiply an inequality by a negative number, the direction of the inequality sign must be reversed:

x<205x < \frac{20}{-5} x<4x < -4

The correct answer is: B. x<4\text{B. } x < -4
