Determine whether the following statement is true or false.
{x| x is a natural number less than 8} = {1, 2, 3, 4, 5, 6, 7, }

Recall that {x | x is a natural number less than 8} means the set of all element x such that x is a natural number less than 8.
Note {1, 2, 3, 4, 5, 6, 7} consists of all numbers satisfying these conditions.
Therefore, the statement is true.
