Which of the following best describes the fundamental difference between the solution to a linear equation (e.g., $ax+b=c$) and a linear inequality (e.g., $ax+b>c$)?

Solve the inequality $2(x-3)+x\le 8$ and show the steps to isolate $x$.

Solve the inequality for $x$.

A student starts with the inequality $x>4$. They multiply both sides by $-1$ and write the result as $-x>-4$. Evaluate whether the student's transformation is correct and provide the proper result if not.

A storage company charges a one-time setup fee of $\mathrm{\backslash (}35$ and a monthly fee of $\mathrm{\backslash )}20$. You want the total cost to be strictly less than $\$200$. Let $m$ be the number of months. Set up the inequality and determine the maximum whole number of full months you can rent storage.
