olve \( n+7.1=8.6 \). Write your answer as a decimal to

To solve the equation \( n + 7.1 = 8.6 \), you need to isolate \( n \). Subtract 7.1 from both sides of the equation: \[ n = 8.6 - 7.1 \] This simplifies to: \[ n = 1.5 \] So the solution is \( n = 1.5 \). To add a little fun, did you know that the concept of isolating variables has roots in ancient times? Algebra, as we know it today, evolved significantly from the works of Persian mathematicians like Al-Khwarizmi in the 9th century! He taught us not just how to solve equations, but also how to write them in a systematic manner. In the real world, the skills you’re honing while solving equations like this one can help you with budgeting, cooking, or even rearranging furniture! Think about it: if you want to calculate how much money you’ve left after a purchase or adjust a recipe based on servings, mastering simple equations is the way to go!
