Solving equations involves finding the value of a variable that makes the equation true. An equation typically consists of two expressions separated by an equal sign. For example, in the equation 2x + 3 = 7, the goal is to determine the value of x that satisfies the equation. To solve an equation, you can use various methods, such as isolating the variable on one side. This often involves performing the same operation on both sides of the equation. For instance, subtracting 3 from both sides of the previous example leads to 2x = 4, making it easier to find that x = 2.
