    6.5

    Explanation:

    • Let “number” be “n”
    25 - 2n = 12

    • Reverse the operations and find “n”
    12 + 2n = 25

    • But since you can’t find “n” because of the lack of information, you should subtract the constants/non-variables
    25 - 12 = 13 or 2n

    • Divide 13 by 2 to get “n”
    13/2 = 6.5

    • Therefore, “n” or “number” is *6.5*

    1. 2(x²)= 32

    2. 25-(2x)= 12

    3. (2x)+8= 14

    4. (x-9)²= 25
