#x<=-25#

Explanation:

This phrase can be expressed algebraically as:

#x+7<=-18#

Here, "some number" is represented by the variable #x#.

To solve this, simply subtract #7# from both sides.

#x<=-25#

This means that the number is any number less than or equal to #-25#. This includes numbers like #-25#, #-90#, and #-100891.2#.

There is no one specific number that can answer this question. Rather, there are an infinite amount of valid solutions for #x#.
