Which of the following equations has no solutions? (1 point) - 6x + 4 = 6x + 3; 6x + 3 = - 6x + 3; 6x + 4 = 6x + 4 O - 6x + 4 = - 6x + 3

5 answers

To determine which of the given equations has no solutions, let's analyze each one:

  1. Equation: \( 6x + 4 = 6x + 3 \)

    • Subtract \( 6x \) from both sides:
    • \( 4 = 3 \) (This is false, hence no solutions.)
  2. Equation: \( 6x + 3 = -6x + 3 \)

    • Add \( 6x \) to both sides:
    • \( 12x + 3 = 3 \)
    • Subtract 3 from both sides:
    • \( 12x = 0 \) ⇒ \( x = 0 \) (This has a solution.)
  3. Equation: \( 6x + 4 = 6x + 4 \)

    • Subtract \( 6x + 4 \) from both sides:
    • \( 0 = 0 \) (This is always true, hence infinitely many solutions.)
  4. Equation: \( -6x + 4 = -6x + 3 \)

    • Add \( 6x \) to both sides:
    • \( 4 = 3 \) (This is false, hence no solutions.)

From the above analysis, the equations that have no solutions are:

  • \( 6x + 4 = 6x + 3 \)
  • \( -6x + 4 = -6x + 3 \)

Thus, both \( 6x + 4 = 6x + 3 \) and \( -6x + 4 = -6x + 3 \) have no solutions. However, since you are looking for a single equation, either of those can be the correct answer depending on which one you want to highlight.

The two equations with no solutions are:

  • \( 6x + 4 = 6x + 3 \) (also indicated, but just one is needed)
  • \( -6x + 4 = -6x + 3 \)

Choose one of them based on your required answer.

So which one

The first equation you provided that has no solutions is:

\( 6x + 4 = 6x + 3 \)

This equation is the simplest and directly shows that \( 4 = 3 \), which is false, thus it has no solutions.

You could also mention the second equation \( -6x + 4 = -6x + 3 \) as it also has no solutions, but according to your request for just one, the most straightforward answer is:

\( 6x + 4 = 6x + 3 \).

My answer choices are
- 6x + 4 = 6x + 3
6x + 3 = - 6x + 3
6 + 4 = 6x + 4
- 6x + 4 = - 6x + 3

Thank you for providing the clear answer choices. Let's evaluate each option to see which has no solutions:

  1. \( 6x + 4 = 6x + 3 \)

    • Subtract \( 6x \) from both sides:
      \( 4 = 3 \)
    • This is false. No solutions.
  2. \( 6x + 3 = -6x + 3 \)

    • Add \( 6x \) to both sides:
      \( 12x + 3 = 3 \)
    • Subtract \( 3 \) from both sides:
      \( 12x = 0 \)
    • Thus, \( x = 0 \). This has a solution.
  3. \( 6 + 4 = 6x + 4 \)

    • This should probably read \( 6x + 4 = 6 + 4 \).
    • If we rewrite it:
    • \( 6x + 4 = 10 \)
    • Subtract \( 4 \) from both sides:
      \( 6x = 6 \)
    • Thus, \( x = 1 \). This has a solution.
  4. \( -6x + 4 = -6x + 3 \)

    • Add \( 6x \) to both sides:
      \( 4 = 3 \)
    • This is false. No solutions.

Conclusion

The equations that have no solutions from your provided options are:

  • \( 6x + 4 = 6x + 3 \)
  • \( -6x + 4 = -6x + 3 \)

Since you need to choose one answer, the first option is the most straightforward:

\( 6x + 4 = 6x + 3 \).
