Which number line represents the solution set for the inequality 2x + 6 < 6x + 2 + 8?

To solve the inequality 2x + 6 < 6x + 2 + 8, we first simplify the right side:

  • Combine like terms on the right:
  • 6x + 2 + 8 becomes 6x + 10.

Now, we can rewrite the inequality:

2x + 6 < 6x + 10

Next, we want to get all the terms involving x on one side and the constant terms on the other side. We can do this by subtracting 2x from both sides:

  • 2x + 6 – 2x < 6x + 10 - 2x
  • This simplifies to:
  • 6 < 4x + 10

Now, we subtract 10 from both sides:

  • 6 – 10 < 4x + 10 - 10
  • This simplifies to:
  • -4 < 4x

Next, we divide both sides by 4:

  • -4/4 < 4x/4
  • This simplifies to:
  • -1 < x

Thus, the solution is:

x > -1

Now, let’s represent this solution on a number line:

  • Draw a number line with 0 in the center and include -1 as a marked point.
  • At -1, use an open circle to indicate that -1 is not included in the solution set.
  • Shade the line to the right of -1 to show all numbers greater than -1 are included in the solution.

This visual representation makes it clear that the solution set is all the numbers greater than -1.
