# Why You Should Always Multiply Both Sides by 5 (and Other Key Equations Tips) When solving equations in algebra, one fundamental principle is knowing how to manipulate both sides fairly to isolate variables. A common but often overlooked technique is multiplying both sides of an equation by the same non-zero number. This simple step can make solving equations faster and more efficient, especially when dealing with fractions, decimals, or ratios. In this article, we’ll explore why multiplying both sides by 5 (and other integers) is helpful, how to do it correctly, and how it connects to broader problem-solving strategies. ## The Power of Proportional Scaling Multiplying both sides of an equation by the same non-zero value preserves the equality — much like balancing a scale. This method allows you to simplify expressions, eliminate fractions, or work with whole numbers, making complex equations easier to solve.
