Two sets of prompts:
Prompt A:
Please solve this problem step by step.
Ensure that each step is detailed and includes the exact arithmetic calculations.
Verify the correctness of each step before proceeding.
After completing all steps, provide only the final solution without including the detailed steps.
"Printed Problem Statement": " \\(\\frac{x+2}{x} = \\frac{5}{3}\\)  "
Prompt B:
”Please solve this problem step by step to ensure accuracy.
After solving, only provide the final solution without including the detailed steps.“
Printed Problem Statement": " \\(\\frac{x+2}{x} = \\frac{5}{3}\\)  ",
The right answer to the equation is X=3;
Prompt A gives the correct answer, while Prompt B gives the wrong answer. However, the output from Prompt A is particularly verbose, nearly four times that of Prompt B.
Questions:

Using Prompt A, I would like the output to be concise, like “(x = 3)”.Not a complex output like the one in the picture.

Is there a better prompt than A that can provide the correct answer while minimizing GPT’s computational process?
I hope someone can successfully tackle this challenge.
Prompt A：
Prompt B：
