Answer:
x ≥ 4
Explanation:
The given statement is "The difference of 10 and a number is at most six".
Let "x" be the unknown number.
"The difference of 10 and a number" can be represented as either "10 - x" or "x - 10", depending on whether x < 10 or x > 10.
"Is at most six" means it is less than or equal to six.
Therefore, we have two potential cases:

Solving the inequalities:

[Remember that when dividing both sides of an inequality by a negative number, we have to reverse the inequality sign.]
Therefore, the two possible solutions are:
If we take the statement "the difference between 10 and a number" as "10 - x" then the solution is x ≥ 4.
