Let's evaluate each expression to determine which have a solution of 3:

  1. \(-2 + 5 = 3\) (This one has a solution of 3)

  2. \(-2 + 5 = 3\) (This is the same as the first; it also has a solution of 3)

  3. \(2 - (-5) = 2 + 5 = 7\) (This does not have a solution of 3)

  4. \(2 - (-5) = 2 + 5 = 7\) (This is the same as the third; it does not have a solution of 3)

  5. \(-5 - (-8) = -5 + 8 = 3\) (This one has a solution of 3)

  6. \(-5 - (-8) = -5 + 8 = 3\) (This is the same as the fifth; it also has a solution of 3)

  7. \(5 + (-8) + 6 = 5 - 8 + 6 = 3\) (This one has a solution of 3)

  8. \(5 + (-8) + 6 = 5 - 8 + 6 = 3\) (This is the same as the seventh; it also has a solution of 3)

  9. \(5 + (-2) = 5 - 2 = 3\) (This one has a solution of 3)

  10. \(5 + (-2) = 5 - 2 = 3\) (This is the same as the ninth; it also has a solution of 3)

  11. \(-5 + 2 = -3\) (This does not have a solution of 3)

Now, compiling the results, the expressions that have a solution of 3 are:

  • \(-2 + 5\)
  • \(-2 + 5\)
  • \(-5 - (-8)\)
  • \(-5 - (-8)\)
  • \(5 + (-8) + 6\)
  • \(5 + (-8) + 6\)
  • \(5 + (-2)\)
  • \(5 + (-2)\)

The final answers are:

  • \(-2 + 5\)
  • \(-5 - (-8)\)
  • \(5 + (-8) + 6\)
  • \(5 + (-2)\)
