Hmmm assuming you meant "is 18 less than the larger number".

let's say the numbers are "a" and "b".

a = smaller number
b = larger number

a = b - 18

\bf \begin{cases}
a+b=62\\
\boxed{a}=b-18\\
----------\\
\left( \boxed{b-18} \right)+b=62
\end{cases}
\\\\\\
2b-18=62\implies 2b=80\implies b=\cfrac{80}{2}\implies b=40

what's a?  well, a = b - 18.
