Anumber increased by five is equivalent to twice the same number decreased by seven

The unknown number is 12.

Step-by-step explanation:

Let the unknown number be 'x'

Given:

A number increased by 5 is equivalent to twice the same number decreased by 7.

So, 'x' increased by 5 means add 5 to 'x'. This gives

Now, is equivalent to twice of 'x' decreased by 7.

Twice of 'x' means 2 times of 'x' which is

'2x' decreased by 7 means subtract 7 from '2x'. This gives,

Now, and are equivalent meaning they are equal. So,

Therefore, the unknown number is 12.
