Answer:

Below!

Explanation:

She can substitute the value of x into the equation. If the equation is equal, then she is correct. Please consider checking my solution.

  • 14{8 + 4(-131/61)} = 6(-131/61) - {5 - 11(-131/61)}
  • => 14{488/61 - 524/61) = -786/61 - {305/61 + 1441/61}
  • => 14{-36/61} = -786/61 - {1746/61}
  • => -504/61 = -786/61 - 1746/61
  • => -504/61 = -2532/61
  • => 504/61 ≠ 2532/61

Since both are not equal, Jordan is wrong. Jordon must find his mistake.

In the equation, she made a mistake in step 2. When she was multiplying the minus with the inside value of bracket, everything must be multiplied by a minus. When a minus gets multiplied with a minus, it becomes a plus sign. She didn't realize that.

Hoped this helped.
