To represent "a number is decreased by 1" in algebraic form using \( x \) for "a number," you would write the expression as \( x - 1 \). This shows that you're taking the variable \( x \) and subtracting 1 from it. Simple, right? When you think about real-world applications, this expression can be used in various contexts, like budgeting. For instance, if you have \( x \) dollars and you spend 1 dollar, you can express your remaining funds as \( x - 1 \). It's a great way to visualize financial changes!
