The video tutorial explains how to form inequalities from verbal statements. It covers four main examples: the sum of a number and five being less than nine, the opposite of the difference of a number and seven being greater than or equal to three times the sum of the number and four, fifteen being greater than the opposite of five times the sum of a number and one, and eight minus a number being less than or equal to three times the number. Each example is broken down step-by-step, showing how to translate words into mathematical expressions and inequalities.

What is the inequality for the sum of a number and five being less than nine?

• n - 5 < 9

• n + 5 > 9
