If you subtract 3 from twice a number the result is 25?
Let the number be represented by ( x ). According to the problem, twice the number minus 3 equals 25, which can be written as the equation ( 2x - 3 = 25 ). Adding 3 to both sides gives ( 2x = 28 ), and dividing both sides by 2 results in ( x = 14 ). Therefore, the number is 14.
