Classify each equation as having No Solution, One Solution, or Infinitely Many Solutions

-4x + 4x = 0
-x = 7x - 8x
5-x=-x
x+4=x+3
9=3(5x-2)
6x-(3x+8) = 16

1 answer

Let's analyze each equation step by step to classify them.

  1. Equation: \(-4x + 4x = 0\)

    Simplification: \[0 = 0\]

    Classification: Infinitely Many Solutions (since both sides are equal for any value of \(x\)).


  1. Equation: \(-x = 7x - 8x\)

    Simplification: \[-x = -x\]

    Classification: Infinitely Many Solutions.


  1. Equation: \(5 - x = -x\)

    Simplification: \[5 = -x + x\] \[5 = 0\]

    Classification: No Solution (since 5 cannot equal 0).


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

    Simplification: \[x - x + 4 = 3\] \[4 = 3\]

    Classification: No Solution (since 4 cannot equal 3).


  1. Equation: \(9 = 3(5x - 2)\)

    Simplification: \[9 = 15x - 6\] \[15 = 15x\] \[x = 1\]

    Classification: One Solution (\(x = 1\)).


  1. Equation: \(6x - (3x + 8) = 16\)

    Simplification: \[6x - 3x - 8 = 16\] \[3x - 8 = 16\] \[3x = 24\] \[x = 8\]

    Classification: One Solution (\(x = 8\)).


Summary of Classifications:

  1. Infinitely Many Solutions
  2. Infinitely Many Solutions
  3. No Solution
  4. No Solution
  5. One Solution
  6. One Solution
