Introduction

In this article, we will focus on solving the given inequality 7x−8 \textgreater 347x - 8 \ \textgreater \ 34. We will use algebraic methods to isolate the variable xx and determine the correct solution. The inequality is a linear inequality, and we will use the properties of linear inequalities to solve it.

Understanding the Inequality

The given inequality is 7x−8 \textgreater 347x - 8 \ \textgreater \ 34. This means that the expression 7x−87x - 8 is greater than 3434. To solve this inequality, we need to isolate the variable xx.

Adding 8 to Both Sides

To isolate the variable xx, we can add 88 to both sides of the inequality. This will give us:

7x−8+8 \textgreater 34+87x - 8 + 8 \ \textgreater \ 34 + 8

Simplifying the left-hand side, we get:

7x \textgreater 427x \ \textgreater \ 42

Dividing Both Sides by 7

To isolate the variable xx, we can divide both sides of the inequality by 77. This will give us:

7x7 \textgreater 427\frac{7x}{7} \ \textgreater \ \frac{42}{7}

Simplifying the left-hand side, we get:

x \textgreater 6x \ \textgreater \ 6

Conclusion

Therefore, the correct solution to the inequality 7x−8 \textgreater 347x - 8 \ \textgreater \ 34 is x \textgreater 6x \ \textgreater \ 6. This means that the value of xx must be greater than 66.

Comparison with Other Options

Let's compare our solution with the other options:

  • Option A: x \textgreater 357x \ \textgreater \ 3 \frac{5}{7}
  • Option B: x \textless 357x \ \textless \ 3 \frac{5}{7}
  • Option C: x \textless 6x \ \textless \ 6
  • Option D: x \textgreater 6x \ \textgreater \ 6

Our solution is x \textgreater 6x \ \textgreater \ 6, which is option D. Therefore, the correct answer is option D.

Final Answer

The final answer is option D: x \textgreater 6x \ \textgreater \ 6.

Q&A Guide

Q: What is a linear inequality?

A: A linear inequality is an inequality that can be written in the form ax+b \textgreater cax + b \ \textgreater \ c, where aa, bb, and cc are constants. For example, 2x+3 \textgreater 52x + 3 \ \textgreater \ 5 is a linear inequality.

Q: How do I solve a linear inequality?

A: To solve a linear inequality, you can add or subtract the same value from both sides, and then divide both sides by the same non-zero value. For example, to solve the inequality 2x+3 \textgreater 52x + 3 \ \textgreater \ 5, you can subtract 33 from both sides to get 2x \textgreater 22x \ \textgreater \ 2, and then divide both sides by 22 to get x \textgreater 1x \ \textgreater \ 1.

Q: What is a quadratic inequality?

A: A quadratic inequality is an inequality that can be written in the form ax2+bx+c \textgreater dax^2 + bx + c \ \textgreater \ d, where aa, bb, cc, and dd are constants. For example, x2+4x+4 \textgreater 0x^2 + 4x + 4 \ \textgreater \ 0 is a quadratic inequality.

Q: How do I solve a quadratic inequality?

A: To solve a quadratic inequality, you can factor the quadratic expression, and then use the sign of the expression to determine the solution. For example, to solve the inequality x2+4x+4 \textgreater 0x^2 + 4x + 4 \ \textgreater \ 0, you can factor the expression as (x+2)2 \textgreater 0(x + 2)^2 \ \textgreater \ 0, and then use the sign of the expression to determine that the solution is x \textless −2x \ \textless \ -2 or x \textgreater −2x \ \textgreater \ -2.

Q: What is the difference between a linear inequality and a quadratic inequality?

A: A linear inequality is an inequality that can be written in the form ax+b \textgreater cax + b \ \textgreater \ c, where aa, bb, and cc are constants. A quadratic inequality is an inequality that can be written in the form ax2+bx+c \textgreater dax^2 + bx + c \ \textgreater \ d, where aa, bb, cc, and dd are constants.

Q: How do I determine the solution to a linear inequality?

A: To determine the solution to a linear inequality, you can use the following steps:

  1. Add or subtract the same value from both sides of the inequality.
  2. Divide both sides of the inequality by the same non-zero value.
  3. Use the sign of the expression to determine the solution.

Q: How do I determine the solution to a quadratic inequality?

A: To determine the solution to a quadratic inequality, you can use the following steps:

  1. Factor the quadratic expression.
  2. Use the sign of the expression to determine the solution.
  3. Use the zeros of the quadratic expression to determine the solution.

Q: What are some common mistakes to avoid when solving inequalities?

A: Some common mistakes to avoid when solving inequalities include:

  • Not following the order of operations.
  • Not using the correct signs when adding or subtracting values.
  • Not dividing both sides of the inequality by the same non-zero value.
  • Not using the correct method to determine the solution.
