Math Problem Statement

Solve the inequality: -3x + 5 ≥ 4x + 5

Solution

To solve the inequality 3x+54x+5-3x + 5 \geq 4x + 5, follow these steps:

  1. Isolate the variable term: Move all terms involving xx to one side of the inequality.

3x+54x+5-3x + 5 \geq 4x + 5

Subtract 4x4x from both sides:

3x4x+55-3x - 4x + 5 \geq 5

This simplifies to:

7x+55-7x + 5 \geq 5

  1. Isolate the constant term: Move all constant terms to the other side of the inequality.

Subtract 5 from both sides:

7x+5555-7x + 5 - 5 \geq 5 - 5

This simplifies to:

7x0-7x \geq 0

  1. Solve for xx: Divide both sides by 7-7. Remember that dividing by a negative number reverses the inequality sign.

x07x \leq \frac{0}{-7}

Simplifying this:

x0x \leq 0

So, the solution to the inequality is:

x0x \leq 0

  1. What happens to the inequality sign when you divide or multiply both sides by a negative number?
  2. How do you solve an inequality when variables are present on both sides?
  3. Can you provide an example of solving an inequality with fractions?
  4. What are the steps to graphing the solution of an inequality on a number line?
  5. How does solving a compound inequality differ from a single inequality?

Tip: Always remember to flip the inequality sign when multiplying or dividing both sides of an inequality by a negative number.
