The video tutorial explains how to translate verbal statements into algebraic expressions using the variable x. It covers two examples: one involving addition and the other multiplication. The first example translates 'the sum of a number increased by three and the number decreased by 20' into an algebraic expression. The second example translates 'the product of twice a number and seven more than five times a number' into an expression. The tutorial emphasizes understanding terms like 'sum' and 'product' and how they relate to algebraic operations.
