4x+13=7(x-2)+bxIf the linear equation above has no solution, which of the following could be the value of b?

Correct answer: C. -3

  • A. -1
  • B. -2
  • C. -3
  • D. -4

Explanation

If a linear equation has the same coefficients and the same constants on opposite sides of the equation, it has no solutions. Option A and Option B have different coefficients for x, making them incorrect. Option D also has unequal coefficients, rendering it incorrect. Option C, with b = -3, results in the coefficients being equal on both sides of the equation, leading to no solution, which is the correct answer.
