Introduction

In this article, we will be solving the inequality 2x16326x2x - 16 \geq 32 - 6x. This is a linear inequality, which means it can be solved using basic algebraic operations. We will use the properties of inequalities to isolate the variable xx and find the solution set.

Understanding the Inequality

The given inequality is 2x16326x2x - 16 \geq 32 - 6x. To solve this inequality, we need to isolate the variable xx on one side of the inequality sign. We can start by adding 6x6x to both sides of the inequality to get:

2x+6x16322x + 6x - 16 \geq 32

Combining Like Terms

Next, we can combine the like terms on the left-hand side of the inequality:

8x16328x - 16 \geq 32

Adding 16 to Both Sides

Now, we can add 16 to both sides of the inequality to get:

8x488x \geq 48

Dividing Both Sides by 8

Finally, we can divide both sides of the inequality by 8 to get:

x6x \geq 6

Conclusion

Therefore, the solution to the inequality 2x16326x2x - 16 \geq 32 - 6x is x6x \geq 6. This means that any value of xx that is greater than or equal to 6 is a solution to the inequality.

Checking the Answer Choices

Let's check the answer choices to see which one matches our solution:

  • A. x12x \geq -12: This is not the correct solution, as our solution is x6x \geq 6, not x12x \geq -12.
  • B. x6x \geq 6: This is the correct solution, as our solution is x6x \geq 6.
  • C. x12x \leq -12: This is not the correct solution, as our solution is x6x \geq 6, not x12x \leq -12.
  • D. xx \leq \emptyset: This is not the correct solution, as our solution is x6x \geq 6, not xx \leq \emptyset.

Final Answer

The final answer is B. x6x \geq 6.

Step-by-Step Solution

Here is the step-by-step solution to the inequality:

  1. Add 6x6x to both sides of the inequality: 2x+6x16322x + 6x - 16 \geq 32
  2. Combine like terms: 8x16328x - 16 \geq 32
  3. Add 16 to both sides of the inequality: 8x488x \geq 48
  4. Divide both sides of the inequality by 8: x6x \geq 6
