Let the unknown number be \( x \). According to the problem, when seven is added to this number, the result is 20. We can write this as an equation:
\[
x + 7 = 20
\]
To solve for \( x \), subtract 7 from both sides:
\[
x = 20 - 7
\]
\[
x = 13
\]
So, the number is \( 13 \).
\[
x + 7 = 20
\]
To solve for \( x \), subtract 7 from both sides:
\[
x = 20 - 7
\]
\[
x = 13
\]
So, the number is \( 13 \).
