To determine which equation has no solution, we can simplify each option and see if they lead to a contradiction.

Option A:

\[ 2x + 17 - 7x - 6 = 8 - 10x - 19 + 5x \]

Combine like terms: \[ -5x + 11 = -10x - 11 + 5x \] \[ -5x + 11 = -5x - 11 \]

Add \( 5x \) to both sides: \[ 11 = -11 \] (This is a contradiction.)

Option B:

\[ 7 + 16x + 1 - 4x = 24 + 8x - 9 + 3x \]

Combine like terms: \[ 8 + 12x = 24 + 11x \]

Subtract \( 11x \) from both sides: \[ 8 + x = 24 \]

Subtract 8 from both sides: \[ x = 16 \]

(This has a solution.)

Option C:

\[ 9x - 3 + 2x + 20 = 15 + 4x + 2 + 7x \]

Combine like terms: \[ 11x + 17 = 15 + 11x \]

Subtract \( 11x \) from both sides: \[ 17 = 15 \]

(This is a contradiction.)

Option D:

\[ 12 - 6x + 4 - x = 3 + 8x + 13 - 11x \]

Combine like terms: \[ 16 - 7x = 16 - 3x \]

Add \( 3x \) to both sides: \[ 16 - 7x = 16 - 3x \]

Subtract 16 from both sides: \[ -7x = -3x \]

Add \( 3x \) to both sides: \[ -4x = 0 \]

This gives \( x = 0 \) (This has a solution.)

Conclusion:

The equations with contradictions (no solutions) are:

  • Option A: \( 11 = -11 \)
  • Option C: \( 17 = 15 \)

However, as you only asked for one option, Option A is a satisfactory answer since it is the first one.
