The equation "2X = 8" represents a simple algebraic expression where X is a variable. To solve for X, you need to isolate it on one side of the equation. This can be done by dividing both sides by 2, which gives you X = 4. In this context, the number 2 is a coefficient, and 8 is a constant. This equation shows a linear relationship, meaning that for every increase in X, the left side of the equation will change proportionally. Understanding such equations is fundamental in algebra and helps in solving more complex mathematical problems.
