Solution

Forming an expression:
Let us suppose, that number is $x,$
we need to write the expression where we have " $15$ more than twice of this number $x$ " ,
Since, two times( twice) of this number $x$ is $2 x$ ,
Now, we will add $2 x$ in $15$ ,
we get, $2 x + 15$
Hence, the expression for the given case is $2 x + 15$ .
