When 12 is subtracted from a certain number, the result is equal to 25 added to twice the number. Find the number

Answer 1

Let's say the certain number is x.

According to the problem, the equation can be written as:

x - 12 = 25 + 2x

Now, we can solve the equation to find the value of x.

First, we can simplify the equation by subtracting x from both sides:

-12 = 25 + x

Next, we can subtract 25 from both sides:

-12 - 25 = x

-37 = x

Therefore, the certain number is -37.
