The statement "X Equals 4" indicates that the variable X has a value of 4. In mathematics, variables are symbols used to represent numbers or values that can change. When we say X equals 4, we are defining the specific value of X in a given context, such as an equation or a function. This concept is fundamental in algebra, where equations often involve finding the value of a variable. For example, if we have the equation X + 2 = 6, we can determine that X equals 4 by subtracting 2 from both sides. Understanding this principle is essential for solving various mathematical problems.
