Solution

Let us take the number with the unknown value to be $x$ .
Now, when we add $5$ to that number, we get $x + 5$ .
We know that when we add $5$ to that number, we get $15$ .
Hence, $x + 5 = 15$
To find the value of the unknown quantity, i.e., $x$ , we need to subtract $5$ on both sides of the equation
$x + 5 - 5 = 15 - 5$
$x = 10$
