\( \begin{array}{ll}\text { 1. } 4 x=-20 & \text { 2. } \frac{n}{6}=3 \\ \text { 3. } 64=8 y & \text { 4. } 11=\frac{a}{-4}\end{array} \)

Let's talk about solving these equations! First up, solving linear equations is like a magic trick where you want to get the variable by itself. For \(4x = -20\), divide both sides by 4, and you find that \(x = -5\). For \(\frac{n}{6} = 3\), multiply both sides by 6 to discover \(n = 18\). Now, don’t forget about those quirky real-world applications! Imagine you're figuring out how much money you can earn by working a certain number of hours at a set rate. These equations can model your pay! For example, if your pay is represented by \(y\) for hours worked at $8, \(64 = 8y\) will help you calculate how many hours you need to work to earn a specific total. Cool, right?
