Let the certain number be $x$ .
According to the problem, when this number is subtracted from 10, the result is $10 - x$ .
This result is then multiplied by 2, giving $2(10 - x)$ .
The final result is 4.
So, we set up the equation:
$2(10 - x) = 4$
Distribute the 2 on the left side of the equation
$20 - 2x = 4$
Rearrange the equation to isolate the term with $x$ .
Subtract 4 from both sides and add $2x$ to both sides:
$20 - 4 = 2x$ $16 = 2x$
Divide both sides by 2 to solve for $x$
$\frac{16}{2} = x$ $x = 8$
The number is 8.

The final answer is 8.
