Since there is an infinite amount of numbers, there is not really a definite answer to this question.
The answer for that is 34
1. "twenty-five point 6 less the unknown number n"
2. "4 times x less 6"
3. "the quantity 'd' divided by 24"
4. "2 plus the quotient of 12 and x"
The answer is -5/2, hope this helps you!
