Identify Operation: Identify the operation needed to isolate f. In the inequality f + 2 < 7, the number 2 is being added to f. To isolate f, we need to use the opposite operation, which is subtraction.
Subtract 2: Subtract 2 from both sides of the inequality to solve for f. f + 2 < 7f + 2 - 2 < 7 - 2f < 5
