To solve the equation \( x + 4 = 28 \), you want to isolate \( x \) by getting rid of the \( +4 \). Subtract 4 from both sides: \( x + 4 - 4 = 28 - 4 \), which simplifies to \( x = 24 \). So, the solution is \( x = 24 \). Did you know that solving equations like this is fundamental in algebra and helps you understand more complex mathematical concepts later on? It's the building block for everything from basic arithmetic to advanced calculus! Equations appear everywhere in daily life—think about budgeting your finances, measuring ingredients in cooking, or even planning a trip. Mastering these skills leads to better decision-making!
